The Fascinating (and Sometimes Ridiculous) History of Doors

The Fascinating (and Sometimes Ridiculous) History of Doors – From Cavemen to Custom Industrial Doors at Calumet Lumber

Let’s be real…doors don’t get enough credit. They stand there, quietly doing their job, opening and closing, keeping the world in (or out). But when was the last time you truly appreciated a door?

Well, today’s the day.

We’re diving into the long (and surprisingly dramatic) history of doors—from prehistoric rock slabs to NASA’s 45-minute mega-doors, and right up to Calumet Lumber Inc. where we build custom industrial doors on-site and can special order any door you might need—with or without windows. (Yes, even those weirdly specific ones you didn’t know existed.)

The Evolution of Doors: From Cavemen to Castles

The first doors weren’t much more than big rocks strategically rolled in front of cave openings to keep out predators. Functional? Yes. Convenient? Not so much.

By the time the Ancient Egyptians came around, doors became status symbols. They crafted massive wooden doors, often adorned with elaborate carvings of gods and pharaohs, proving that even back then, people liked to show off their front entrances. Meanwhile, in Mesopotamia, someone finally invented the hinged door, making it much easier to walk through without pulling a muscle.

The Romans were the first to innovate beyond basic function. They introduced double doors, sliding doors, folding doors, and even early versions of automatic doors using pulleys and steam. Some of their bronze doors were so well-built that they’re still standing today—over 2,000 years later. (If only all doors lasted that long.)

Fast forward to the Middle Ages, and doors became less about aesthetics and more about survival. Thick wooden doors reinforced with iron bars and spikes became essential for castle security. Some had hidden passageways and murder holes—which, as you may have guessed, were used to pour boiling oil on unwelcome guests. Medieval door technology was all about keeping people out (and sometimes keeping them in).

The Doorknob Revolution: Thank You, Osbourn Dorsey

For most of human history, opening a door required pulling a string, sliding a wooden latch, or just shoving the thing really hard. That all changed in 1878 when Osbourn Dorsey, an African American inventor, revolutionized door technology with his patent for a door-closing mechanism—the foundation of the modern doorknob and door latch.

Now, you might be thinking, "Wait, we didn’t have doorknobs before 1878?!" Nope. Most people were still tying leather straps around wooden pegs or—brace yourself—sticking their fingers into knotholes to pull doors open. (Yes, people willingly did this. No, we don’t want to think about the hygiene implications.)

Dorsey’s invention changed everything. It provided a secure, easy-to-use locking mechanism that was durable and reliable. But despite his contribution, Dorsey’s life remains largely undocumented—a frustratingly common fate for many Black inventors of his time. He didn’t receive fame, fortune, or even a Wikipedia page (seriously, someone should fix that), but his invention became the backbone of door security as we know it today.

So, next time you casually turn a doorknob, remember: Osbourn Dorsey saved you from sticking your fingers in a hole to open a door. You’re welcome.

Theophilus Van Kannel & The Revolving Door: Because He Hated Holding Doors for People

You ever get stuck in that awkward “Who’s going first?” shuffle at a doorway? Maybe you hold the door, and suddenly a parade of strangers’ marches through while you stand there like an unpaid doorman? Well, Theophilus Van Kannel had enough of that nonsense.

In 1888, he patented the revolving door, and legend has it that his inspiration came from not wanting to hold doors open for other people. Was he just an anti-social genius? Maybe. But his invention made perfect sense.

Revolving doors weren’t just about avoiding awkward social interactions (although that was a perk). They solved a major problem for big buildings: air pressure and wind resistance.

Skyscrapers, especially in cold and windy cities like Chicago and New York, had a problem. Opening a standard door would create a wind tunnel effect, letting in freezing gusts of air in winter and letting out all the expensive heated air. Not ideal.

Van Kannel’s revolving door acted as an airlock, preventing sudden temperature shifts while also keeping pedestrian traffic flowing smoothly. This made them perfect for department stores, office buildings, and hotels, where constant foot traffic made traditional swinging doors a logistical nightmare.

Interestingly, Theophilus Van Kannel never married, which has led to some fun speculation that his frustration with human interaction extended beyond just doorways. Whether or not that’s true, one thing’s for sure: thanks to him, we now have a way to enter buildings without getting smacked in the face by someone’s poorly timed exit.

The 20th Century: Commercial Doors Take Center Stage

By the early 1900s, industrialization and urbanization meant doors needed to be stronger, safer, and more specialized. Steel doors became the norm in factories and public buildings due to their fire resistance, durability, and security.

Automatic doors made their first commercial appearance in the 1950s at a restaurant in Corpus Christi, Texas, where they allowed waiters to pass through hands-free while carrying trays. This innovation quickly spread to hospitals, airports, and department stores, paving the way for the motion-activated doors we use today.

One of the most important safety innovations came in the 1930s: the crash bar (or panic bar). Before this, exit doors often became death traps in emergencies—like the 1903 Iroquois Theatre fire, where over 600 people perished because the doors opened inward and jammed in the chaos. The introduction of crash bars allowed for quick, easy exits, making commercial spaces much safer.

At Calumet Lumber Inc., we know that doors in commercial and industrial settings need to be custom-fit for safety, function, and durability. That’s why we build custom industrial doors on-site, tailored to fire resistance, impact resistance, and security standards—and if you need something specific, we can special order any door, with or without windows.

The Biggest, the Smallest, and the Most Ridiculously Advanced Doors in the World

Let’s talk big doors—because size does matter when you’re launching rockets into space. The largest doors on the planet belong to NASA’s Vehicle Assembly Building at Kennedy Space Center. Standing 456 feet tall, these monstrous doors are three times the height of the Statue of Liberty, proving that when NASA builds something, they go big or go home.

And speaking of home, if you ever feel impatient waiting for your garage door to open, imagine this: NASA’s mega-doors take 45 minutes just to open or close. That’s half a lunch break, an entire episode of your favorite TV show, or about the time it takes to argue over where to eat for dinner. If you ever plan to watch these beasts in action, bring snacks, a chair, and maybe a book—it’s not exactly edge-of-your-seat entertainment.

The doors of NASA's Vehicle Assembly Building (VAB) at Kennedy Space Center are opened for each major rocket launch. This includes the assembly and rollout of rockets like the Space Launch System (SLS) for Artemis missions. The frequency of these openings depends on the launch schedule, which can vary based on mission requirements and readiness.

But while NASA holds the title for biggest doors, the record for the smallest functional door goes to researchers at the University of Cambridge. In 2012, they built a microscopic door that’s just a few micrometers tall—which means you can’t see it without a high-powered microscope. (So don’t bother trying to install one on your office cubicle for privacy.)

This tiny door was designed as part of a nanotechnology experiment, proving that science loves building things just because it can. It actually opens and closes, though you’ll need specialized lab equipment—not a doorknob—to operate it. Sure, it won’t replace your office entrance anytime soon, but it does raise the question: Was this necessary? Probably not. But was it cool? Absolutely.

So, whether it’s a door so massive it could fit a 40-story building inside it, or one so small that even ants would need a microscope to find it—one thing’s clear: humanity will never stop pushing the limits of doors.

The Wacky World of Plywood: A Historical Tale

 

The Wacky World of Plywood: A Historical Tale

A long time ago in a galaxy far, far away (Sorry, I was in Star Wars Mode) ...

Our story begins in the land of pyramids and pharaohs. Yes, you guessed it—ancient Egypt! While the Egyptians are famous for their monumental architecture, they also dabbled in the art of plywood. They glued thin layers of wood together to create a more durable material for their furniture. Little did they know, they were laying the groundwork for a modern marvel. Imagine Cleopatra lounging on a plywood chaise, thinking, "This is way more comfortable than stone!"

Fast forward to ancient Greece, where the Greeks took the Egyptians' idea and ran with it—literally. They refined the technique, using plywood for everything from shields to chariots. The Greeks were all about innovation, and plywood was no exception. Picture a Greek warrior bragging, "My shield is lighter and stronger. Plus, it doubles as a surfboard!"

Then came the Romans, who were never ones to shy away from a good idea. They adopted plywood for their ships, making them sturdier and more seaworthy. The Roman Empire sailed the high seas with plywood at the helm. Imagine a Roman captain shouting, "Full speed ahead! And don't worry, our ship is plywood-proof!"

Jumping ahead to the 19th century, we meet Immanuel Nobel, father of Alfred Nobel. Immanuel realized that several thinner layers of wood bonded together would be stronger than a single thick layer. He invented the rotary lathe, revolutionizing the production of plywood. Picture Immanuel saying, "Eureka! Now we can make furniture that won't collapse under the weight of a good meal!"

In 1928, the first standard-sized 4 ft by 8 ft plywood sheets were introduced in the United States, marking a significant milestone in the history of plywood. This innovation made plywood a staple in construction and design, paving the way for its widespread use today. Imagine a builder in 1928 exclaiming, "Finally, a material that can handle my dance moves on the job site!"

The Renaissance of Plywood

Fast forward to the 20th century, and plywood was making a grand comeback. During World War II, it was used extensively in aircraft construction. Imagine a squadron of plywood planes soaring through the skies! The material was lightweight yet strong, making it perfect for the job. Post-war, plywood found its way into homes, becoming the unsung hero of DIY enthusiasts everywhere.

Ever wondered how a humble tree transforms into the superhero of construction materials? Buckle up, because the magical journey of plywood is about to unfold! It all begins with the log selection, where only the finest tree trunks get their golden ticket to the plywood factory. These logs are then stripped of their bark and chopped into manageable pieces, ready for their spa treatment.

Next, the logs take a hot bath to soften up, before being fed into a lathe that peels them into thin sheets of veneer, like unrolling a giant roll of paper towels. These freshly peeled veneers then hit the sauna to dry out, ensuring they're not too soggy for the next step.

Once dried, the veneers get a generous coating of adhesive and are stacked in layers, with each layer's grain running perpendicular to the previous one. This crisscross pattern is what gives plywood its super strength. The layered veneers are then pressed together under high heat and pressure, bonding them into a single, solid sheet that's tougher than a superhero's cape.

After pressing, the plywood sheets get a makeover, trimmed to size and sanded to perfection, ready to dazzle in their final form. Finally, the plywood undergoes a rigorous quality control check, ensuring only the best boards make it to the market. And there you have it, the magical transformation of a tree into the mighty plywood!

The Benefits of Plywood: Why It’s a Superstar

Move over, Hollywood stars, because plywood is the real superstar here! This versatile wonder material comes with a list of benefits that would make any celebrity jealous. First up, its strength and durability are unmatched, thanks to its cross-grain construction. Plywood laughs in the face of warping, cracking, and splitting, making it the Hulk of building materials. Despite its superhero strength, plywood is surprisingly lightweight, making it easy to handle and transport—no need for a team of bodyguards here!

Plywood is also a budget-friendly option, often more affordable than solid wood, so you can save your pennies without compromising on quality. Its versatility is another feather in its cap, as it can be used for everything from construction to furniture making. Talk about a jack-of-all-trades!

But wait, there's more! Plywood is eco-friendly, using less wood than solid lumber, making it a sustainable choice that Mother Nature would approve of. And let's not forget its aesthetic appeal; with various wood veneers available, plywood can mimic the look of expensive hardwoods at a fraction of the cost. So, next time you're looking for a material that’s strong, lightweight, cost-effective, versatile, eco-friendly, and beautiful, remember that plywood is the true superstar!

The Lumber Size Chronicles: A Comical Guide

Alright, lumber fans let’s take a moment to reflect on the fun side of lumber sizes. Because let’s be honest—wood measurements are about as straightforward as trying to assemble furniture without an instruction manual.

A Legacy of Lumber: Calumet Lumber Inc.

Before we dive too deep into the quirks of lumber sizes, let’s take a moment to appreciate where you’re getting all this top-notch wood from—Calumet Lumber Inc. Established in 1906, this historic company has been supplying quality lumber and building materials for well over a century. It has stood the test of time, growing alongside the industries it supports and adapting to meet the needs of every generation of builders, contractors, and DIYers.

Even more impressive? Calumet Lumber Inc. is a woman-owned business, proving that strength, resilience, and leadership aren’t just for the lumber itself. With a commitment to exceptional service, unmatched expertise, and a passion for all things wood, Calumet Lumber remains the go-to source for every lumber need—from the tiniest trim piece to entire truckloads of timber.

The Mysterious Case of the 2x4

Ah, the legendary 2x4, the Houdini of the lumber world! You’ve heard of it, you’ve used it, and you’ve probably yelled at it once or twice. But have you ever seen a true 2-inch by 4-inch piece of wood? Spoiler alert: you haven’t. Instead, you’re getting 1.5 inches by 3.5 inches. Why? Because wood goes on a diet before it hits your project, shrinking down in the drying and planning process.

It’s kind of like when you order a "large" coffee at a fancy café, and what you get barely qualifies as medium in your mind. It’s still coffee, sure, but it’s just not what you were expecting. The 2x4 is lumber’s version of a little white lie—misleading, but ultimately forgivable.

But let’s dive into the history of this sneaky stick. Back in the day, when lumberjacks were more Paul Bunyan than power tools, a 2x4 was actually cut to a rough 2 inches by 4 inches. However, as the wood dried out, it would shrink a bit. Then, to make it smooth and uniform, it would be planed down, losing a bit more in the process. So, by the time it was ready for your project, it had slimmed down to its current size.

This tradition stuck around, and now we have the modern 2x4, which is more like a 1.5x3.5. It’s kind of like how your grandma’s cookie recipe calls for a “cup” of sugar, but her cup is an old teacup that holds a bit more than a standard measuring cup. It’s all about tradition and a little bit of magic.

So next time you’re working with a 2x4, just remember it’s not lying to you, it’s just keeping up with a long-standing tradition. And maybe, just maybe, it’s trying to help you build character (and a little bit of patience) along with your project.

More Than Just 2x4s

Ah, the 2x4, the superstar of the lumber world! But let's take a trip down memory lane and meet its extended family, each with its own quirky personality and historical significance.

Back in the day, when lumberjacks roamed the forests with axes and flannel shirts, the 2x4 was born. It quickly became the go-to piece for framing houses, earning its place in the lumber hall of fame. But the 2x4 wasn't alone. Its siblings, the 1x2s, 2x6s, 4x4s, and even the mighty 6x12s, each carved out their own niche in the construction world.

The 1x2, often overlooked, is like the little sibling who always wants to help. Perfect for trim work and small projects, it's the unsung hero of the lumber family. Then there's the 2x6, the big brother who steps in when you need a bit more muscle for your framing needs. And let's not forget the 4x4, the sturdy cousin who's always there to support your deck or fence, standing tall and strong.

Now, the 6x12 is the lumber equivalent of a bodybuilder. This massive beam can hold up the weight of your entire project—literally. It's the go-to for those ambitious builds that require serious support. Imagine it flexing its wooden muscles, ready to take on any challenge you throw its way.

And just like any family, the lumber clan has its quirks. Ever wonder why a 2x4 isn't 2 inches by 4 inches? It's a classic case of lumber shrinkage. Originally cut to those dimensions, they shrink during the drying process, leaving us with the slightly smaller versions we know today. It's like the lumber world’s version of a diet plan!

So, whether you need a 1x2 for some delicate trim work or a 6x12 to hold up your dream project, remember that each piece of lumber has its own story and purpose. And for all your lumber needs, head over to Calumet Lumber Inc., your one-stop shop for every piece of wood your project could possibly need.

Bunks: Lumber’s Cozy Bed

Now, let’s talk about bunks. No, this isn’t a new sleepover trend in the world of construction materials. A bunk is a massive stack of lumber—usually around 100 pieces of 2x4s stacked together neatly, ready to be shipped off to their final destination.

Think of it as a lumber slumber party, where all the planks get snug and cozy until it’s their time to shine. It’s a comforting thought, really—hundreds of planks sticking together through thick and thin, waiting for their moment to be turned into a house, a deck, or maybe even a really ambitious treehouse. And yes, if you need a whole bunk, Calumet Lumber Inc. has got you covered.

Truckloads: The Ultimate Lumber Haul

If a bunk isn’t quite enough for you, let’s talk about a full truckload of lumber. This is the granddaddy of lumber orders, where thousands of board feet of wood roll up, ready to take on anything from an entire housing development to a massive commercial project. It’s like ordering a single fry versus getting the entire deep fryer’s worth—go big or go home.

Truckloads of lumber are the backbone of large-scale construction, ensuring that builders, contractors, and ambitious DIYers have all the wood they need in one giant, wood-scented delivery. And, of course, Calumet Lumber Inc. can hook you up with a truckload, whether you’re building a house, a barn, or just want to be the most prepared person on your block.

But let's take a step back in time. Did you know that the history of lumber dates back to ancient civilizations? The Egyptians used wood to build their impressive ships and furniture, while the Romans constructed their famous aqueducts and buildings with timber. Fast forward to the 19th century, and the lumber industry was booming in North America, with logging camps and sawmills popping up like mushrooms after a rainstorm.

In the early 20th century, the invention of the chainsaw revolutionized the industry, making it easier and faster to harvest trees. Today, lumber is still a crucial material in construction, and a truckload of it is like a treasure trove for anyone with a big project in mind.

So, whether you're channeling your inner Pharaoh, Roman engineer, or modern-day builder, a truckload of lumber is your ticket to creating something truly monumental. Just remember, with great lumber comes great responsibility—use it wisely and build something amazing!

Pallets: Lumber’s Magic Carpet

Enter the humble pallet. This flat, wooden platform is basically a travel agent for lumber. It moves everything from your high-end hardwood to the rough plywood you slapped together for that "temporary" fix that somehow became permanent.

Pallets are the unsung heroes of the shipping world—the magical carpets that carry the weight of the global economy without asking for so much as a thank-you. And let’s not forget their second life: when pallets are done with their 9-to-5, they become trendy DIY projects, coffee tables, and backyard planters. Talk about versatility! Speaking of which, you can always pick up a fresh stack of pallets at Calumet Lumber Inc.

But let's rewind a bit. The history of pallets is surprisingly fascinating. The concept of pallets dates back to ancient Egypt, where they used wooden platforms to move heavy loads. Fast forward to World War II, and pallets became essential for military logistics, revolutionizing the way goods were transported and stored. They were the unsung heroes of the war effort, silently supporting the troops by ensuring supplies were efficiently moved.

Today, pallets are everywhere, and their versatility knows no bounds. From supporting global trade to becoming the centerpiece of your DIY project, pallets have truly earned their place in history. So next time you see a pallet, give it a nod of appreciation for its rich history and endless possibilities.

Planks: The Lumber Superstars

Then we have planks—the real MVPs of the lumber universe. Whether they’re framing your new home, forming the foundation of your weekend DIY project, or serving as the dance floor for your cousin’s questionable wedding reception, planks are dependable, sturdy, and let’s be real, stylish.

Planks are the workhorses of the wood world, carrying the weight of our projects on their—well—planks. They don’t ask for much in return, just a little respect and maybe a decent coat of stain. And if your project needs planks, you already know where to go—Calumet Lumber Inc.

But let's not forget the historical significance of planks! These unsung heroes have been around since ancient times. The Egyptians used wooden planks to build their mighty ships, enabling them to navigate the Nile and expand their empire. The Vikings crafted their legendary longships from sturdy planks, allowing them to explore and conquer distant lands. Even the settlers of the American frontier relied on planks to construct their homes and barns, laying the foundation for the nation we know today.

So next time you pick up a plank, remember you're holding a piece of history in your hands. Treat it with the respect it deserves, and it will serve you well, just as it has served countless generations before us.

Apitong: The Exotic Heavyweight Champion

If the lumber world had an all-star roster, Apitong would indeed be the MVP, the LeBron James of the timber league. This exotic wood hails from the lush forests of Southeast Asia, particularly from countries like the Philippines, Malaysia, and Indonesia. It's known for its toughness, durability, and ability to take on just about anything. Imagine Apitong at a lumber red-carpet event, strutting down in a tuxedo, stealing the spotlight from all the other woods. Oak and Maple would be left in the shadows, whispering, "Who is that?"

Historically, Apitong has been the go-to choice for heavy-duty applications. Back in the day, it was used for shipbuilding, proving its mettle on the high seas. Today, it's the top pick for truck beds, trailers, and anywhere that durability matters. If wood were superheroes, Apitong would be the one saving the day while the 2x4 was still trying to figure out why it shrunk in the wash. Picture Apitong swooping in with a cape, rescuing your cargo from the perils of the road.

But wait, there's more! Apitong isn't just a one-trick pony. Here are some other uses for this remarkable wood:

1.      Flooring: Apitong's dense grain and high durability make it an excellent choice for flooring, especially in high-traffic areas

2.     Furniture: Its strength and attractive grain pattern make it ideal for crafting sturdy and beautiful furniture

3.     Marine Applications: Apitong's natural resistance to rot and decay makes it perfect for boat decks and dock construction

4.    Construction: It's used for beams and supports in heavy construction due to its exceptional load-bearing capacity

5.     Decking: Apitong's resilience to weather and wear makes it a great option for outdoor decking

And yes, Calumet Lumber Inc. can get you Apitong, too! So, if you're looking for a wood that's as tough as nails and as stylish as a Hollywood star, Apitong is your go-to choice. 

The Final Cut

So, there you have it—the wild, wonderful, and slightly ridiculous world of lumber sizes and terminology. Whether you’re dealing with a deceptive 2x4, stacking bunks like a lumberjack pro, or dreaming of a life where pallets get the respect they deserve, one thing’s for sure: wood is never boring.

Now go forth, armed with this knowledge, and impress your friends at the hardware store. Or better yet, just head over to Calumet Lumber Inc.—where every size, shape, and type of lumber is ready for your next big project, all backed by a legacy of excellence and leadership in the industry.

Penny Nails

 

Nailed It! The Hilarious History and Handy Tips for Penny Nails

Ever wondered why carpenters are always yammering on about 16d common nails or 8d finish nails, but nobody ever spills the beans on what the heck 'd' means? Well, grab your tool belt and buckle up, because we're about to nail down the details!

The Great Nail Mystery

Once upon a time, in a land far, far away (okay, it was 15th-century England), there was a bustling village full of hardworking carpenters. These carpenters were always in a heated debate about the best nails to use for their projects. One day, a young apprentice named Timmy decided he had enough of the confusion and set out to uncover the truth behind the mysterious 'd' in nail sizes.

Timmy wandered into the village marketplace, where he found Old Man Jenkins, the wisest carpenter in the land. "Old Man Jenkins," Timmy asked, "why do we call them 16d nails? What does the 'd' even mean?"

Old Man Jenkins chuckled and said, "Ah, young Timmy, let me tell you a tale. You see, back in the day, nails were priced by the cost of a 'long hundred'—that's 120 nails. The 'd' stands for 'denarius,' which was a Roman coin and also the name for an English penny. So, a 16d nail would have cost 16 pennies for a hundred of them."

Timmy's eyes widened. "So, it's all about money?"

"Exactly!" Old Man Jenkins replied. "The penny number indicated the price of 120 nails of that size. Bigger nails cost more, just like how a supersized meal costs more at the tavern."

Timmy was amazed. "But why do we still use this system today?"

Old Man Jenkins shrugged. "Some traditions just stick around, like Aunt Mildred's fruitcake at Christmas."

The Modern-Day Nail Saga

Fast forward to today, and we're still using this ancient system to designate nail sizes. A 16d nail is typically 3 1/2 inches long, perfect for those heavy-duty projects. Other common sizes include 6d (2 inches), 8d (2 1/2 inches), and 20d (4 inches). It's like a secret code that only carpenters understand.

Fun Fact: Nail Size and Weight

Did you know that the weight of nails was also a factor in their pricing? Heavier nails cost more because they required more material to produce. So, if you ever feel like your nails are weighing you down, just remember—they're worth their weight in pennies!

But How Long Have Nails Really Been Around?

Nails have been around for a very long time—since ancient times, in fact! Archeologists have found nails in Egypt dating back to around 3,400 B.C. These early nails were made of bronze and had a similar shape and design to the nails we use today. So, the next time you're hammering away, just think—you’re continuing a tradition that’s thousands of years old!

Why You Should Care About Nail Sizes

Understanding nail sizes can make a big difference in your construction projects. Here's why you should care:

1. Strength and Stability Different nail sizes are designed for different tasks. Using the right size ensures that your project is strong and stable. For example, a 16d nail is perfect for framing because it's long and sturdy, while a smaller 6d nail is better for lighter tasks like attaching trim.
2. Preventing Damage Using the wrong size nail can damage your materials. A nail that's too long might split the wood, while one that's too short won't hold things together properly. Knowing the right size helps you avoid these issues.
3. Efficiency When you use the correct nail size, your work goes more smoothly. You won't have to redo parts of your project because the nails didn't hold, saving you time and frustration. And let's be honest, who wants to spend their weekend fixing a wobbly bench?
4. Professional Results Using the right nail size gives your project a professional finish. It ensures that everything is securely fastened and looks neat, which is especially important for visible parts of your work. Impress your friends and family with your carpentry skills!
5. Cost-Effectiveness Choosing the right nail size can also save you money. You won't waste nails by using the wrong ones, and your project will last longer, reducing the need for repairs. More money for snacks and celebratory drinks!
6. Safety Properly sized nails ensure that your structures are safe. Whether it's a piece of furniture or a part of your home, using the right nails helps prevent accidents and injuries. Because nobody wants a surprise visit to the ER.

So there you have it! Next time you're at the hardware store and someone asks you about 16d nails, you can drop some historical knowledge and maybe even get a few laughs. And speaking of 16d nails, why not put that knowledge to good use with a fun DIY project?

Before joining the sales team at Calumet Lumber Inc., I was a high school teacher.  Now, instead of dealing with teenagers’ excuses, I deal with contractors’ requests. Turns out, both jobs require a lot of patience and a good sense of humor!  My expertise in chalk was limited to the white stuff that turned my pants into a dusty mess. One time, I tried to impress my students by drawing a perfect circle on the chalkboard. Let’s just say it ended up looking more like an amoeba. The kids had a good laugh, and I learned that freehand art was not my strong suit.  My only other chalk-related skill was creating sidewalk masterpieces with my great-nieces and nephew.  Have you seen some of that sidewalk chalk art? Some of it looks like you’re about to plunge into a giant crack in the sidewalk! Talk about a “chalky” situation!

I was nutty in the classroom too!

But I digress. So, let’s chat it up about chalk in an industrial construction setting. Imagine using chalk to mark out measurements on a construction site. You’d have to dodge forklifts and cranes while trying to draw a straight line. And let’s not forget the wind – one gust and your carefully drawn line is now a modern art piece. Plus, you’d probably end up with more chalk on your clothes than on the ground. Industrial chalking: where precision meets chaos! Let’s try to tame some of that chaos down and talk Dura Mark products. Exciting news! Calumet Lumber now stocks the Dura Mark line!

DuraMark Marking Chalk: The Rainbow of Construction

SO MUCH COLOR!

When it comes to marking chalk, DuraMark has you covered with a palette that would make even a rainbow jealous. Available in seven vibrant colors, each with its own unique personality, DuraMark is the Michelangelo of the construction world.

Blue (Semi-Permanent): The reliable friend you call for general construction and layout work. It’s like the blue jeans of marking chalk—always in style and ready for anything.

Red (Semi-Permanent): The bold one, often used for more permanent markings like electrical work or plumbing. Think of it as the red-carpet treatment for your construction site.

Yellow (Standard-High Viz): The high-visibility hero, ideal for road construction or safety markings. It’s the construction equivalent of a neon yellow safety vest—impossible to miss.

White (Standard): The classic choice for interior work like drywall or carpentry. It’s the little black dress of marking chalk—simple, elegant, and always appropriate.

Black (Semi-Permanent): The contrast king, perfect for marking on lighter surfaces. It’s like the black Sharpie of the chalk world—bold and unmistakable.

Neon Orange (Standard-High Viz): The flashy cousin of yellow, often preferred for temporary markings. It’s the construction site’s version of a highlighter—bright, bold, and attention-grabbing.

Neon Green (Standard-High Viz): The go-to for landscaping or utility work. It’s like the green

light at an intersection—clear, visible, and signaling “go.”

DuraMark Marking Chalk: Built to Last

DuraMark’s semi-permanent colors (Blue, Red, Black) are like the marathon runners of the chalk world, lasting several months depending on weather and traffic. The standard-high viz colors (Yellow, Neon Orange, Neon Green) are more like sprinters, designed for high visibility but generally lasting a few weeks to a couple of months. The standard white color is somewhere in between, typically lasting a few weeks to a month.

For road work, high-visibility colors are essential. Yellow is perfect for marking lanes and crosswalks, while neon orange is great for temporary markings and construction zones. It’s like having a team of superheroes ensuring safety and clear communication on the roads.

The ChalkShot Pen: Precision in Your Pocket

PEN SIZE TOO!

A handy tool designed for precise and high visibility marking on various surfaces. This versatile pen works on almost any surface, including stucco, tile, brick, wood, and steel. With its bright neon green chalk, it’s like having a laser pointer for your construction projects. Each canister provides over 250 shots, making it efficient for large projects.

Safety First: Chalk It Up to Smart Practices

Yes, even marking chalk comes with its own set of safety precautions:

Inhalation: Avoid breathing in the dust, as it can irritate the respiratory system. Prolonged exposure to crystalline silica dust, which may be present in the chalk, can cause serious lung conditions like silicosis.

Eye Contact: Chalk dust can cause irritation and mechanical abrasion to the eyes. If it gets into your eyes, rinse thoroughly with water and avoid rubbing.

Skin Contact: Prolonged contact with the skin may cause mild irritation. Wearing protective gloves can help prevent this.

Flammability: While the chalk itself is not flammable, finely divided dust can form explosive mixtures in the air. Keep the area well-ventilated and avoid creating dust clouds.

General Handling: Always read and understand all safety precautions before use. Wear appropriate protective equipment, such as gloves and eye protection.
