6 Best Tarp Straps For Securing Hay Bales That Old Farmers Swear By

There’s nothing quite like the feeling of a neatly stacked pile of hay, ready for the winter. But that feeling turns to dread when you see dark clouds rolling in and you’re fumbling with a frayed, over-stretched strap. A good tarp is only half the battle; the straps holding it down are what stand between you and a pile of moldy, useless bales. Choosing the right ones isn’t about spending the most money, but about understanding what the job demands.

Why Quality Tarp Straps Matter for Hay Bales

A cheap tarp strap is one of the most expensive mistakes you can make on a small farm. When one snaps in a 40-mph gust of wind, you aren’t just losing a dollar; you’re risking hundreds of dollars’ worth of hay. The real cost is in the lost feed, the time spent re-stacking, and the frustration of dealing with a problem that was entirely preventable.

The forces acting on a tarp are relentless. It’s not just a single pull; it’s the constant flapping and vibrating from the wind that fatigues the rubber. Add in the sun’s UV radiation baking the strap day after day, and the freezing cold of a winter night making it brittle. A quality strap is engineered to withstand this cycle of abuse, while a cheap one simply counts down the days until it fails.

Think of it as an investment in insurance. You are insuring the quality of your feed and the safety of your property. A loose, flapping tarp can spook animals or get tangled in equipment, and a strap that snaps under tension can become a dangerous projectile. Investing in good straps provides peace of mind that your hard work is protected, come wind or rain.

Keeper EPDM Rubber Straps: The All-Weather Standard

You will find Keeper straps in just about every barn and truck bed for a reason. Their signature feature is the EPDM (ethylene propylene diene monomer) rubber. Unlike natural rubber, which cracks and rots under sun exposure, EPDM is a synthetic compound that is highly resistant to UV rays, ozone, and extreme temperatures.

This means a Keeper strap you put on in the summer heat will still be flexible and strong when you need to pull it off in the dead of winter. They provide a consistent, reliable stretch with strong, zinc-plated steel S-hooks that resist rust. They are the no-nonsense workhorse for securing tarps over square or round bales when you just need something that works, every single time.

The only real tradeoff is their fixed length. You can’t adjust them, so you need to own a variety of sizes (10”, 15”, 21”, 31”, etc.) to have the right tool for the job. You learn to pick the right length by feel, grabbing one that will be under good tension without being stretched to its absolute limit.

Erickson Pro Series: Built for Heavy-Duty Tarping

When you’re covering a large stack that needs to survive a whole season, you step up to something like the Erickson Pro Series. These are noticeably beefier than standard-duty straps. The rubber is often thicker and the S-hooks are made from a heavier gauge of steel, so they won’t bend open when you really have to crank down on a heavy canvas tarp.

The difference is in the details. Look at the ends where the hook is attached; they are often reinforced to prevent the hook from tearing through the rubber under high stress. This is the kind of durability you need when a winter storm is trying to tear the tarp right off your main hay supply. They give you the confidence to secure it and forget it.

This heavy-duty construction comes at a slightly higher price and with a bit less flexibility. They can feel stiff, especially in the cold, and might be overkill for securing a small tarp over a wheelbarrow. But for your most critical loads, that rigidity is exactly what you want.

Rhino USA Adjustable Straps for a Custom Secure Fit

Sometimes a fixed-length strap just isn’t right. Maybe your hay stack is an odd shape, or the tarp grommets don’t line up perfectly with your anchor points. This is where adjustable straps, like those from Rhino USA, shine. They allow you to dial in the perfect amount of tension every time.

Most designs use a simple steel buckle that lets you feed the strap through and pull it tight, removing any slack. This is incredibly useful for re-tightening a tarp after it has settled or stretched over a few weeks. It eliminates the need to unhook and re-hook everything, saving you time and hassle.

The tradeoff for this convenience is an added point of potential failure. The buckle or adjustment mechanism can get clogged with mud, snow, or ice, making it difficult to use. While a solid piece of rubber has less to go wrong, the versatility of an adjustable strap often outweighs this risk, making it an excellent tool to have in your collection for those tricky situations.

Vulcan Tarp Straps: A Top Choice for Durability

If you want to know what holds up, look at what the professional truckers use. Brands like Vulcan build straps to meet the extreme demands of securing loads on the highway, and that quality translates perfectly to the farm. Their reputation is built on long-term durability.

Vulcan often uses proprietary rubber compounds that are obsessively engineered for maximum resistance to the elements. This means they last longer before getting brittle and losing their elasticity. A Vulcan strap might last two or three seasons in conditions that would destroy a cheaper strap in one. They cost more upfront, but their extended lifespan can make them cheaper in the long run.

Pay attention to their S-hooks. They are typically made of high-strength, coated steel that resists both bending and corrosion. After a few years of being exposed to rain, manure, and mud, a cheap hook will be a rusty, bent mess. A Vulcan hook will still be solid, secure, and ready for work.

Tarp-Tie Bungees: The Most Versatile Option

Tarp-Ties are a different animal altogether. Instead of a fixed strap, they offer a highly adjustable bungee cord system with a unique hook and lock design. This makes them the ultimate problem-solvers for securing tarps in awkward spots or around irregular shapes.

Imagine you need to tarp a small hay feeder that’s right next to a fence post. A standard strap might be too long or too short. With a Tarp-Tie, you can loop it around the post, hook it to the grommet, and pull the cord to the exact tension needed. You can also link multiple Tarp-Ties together to create a custom length on the fly.

Their primary limitation is their working load. A heavy-duty EPDM strap is designed for pure, brute-force tension. Tarp-Ties are better suited for lighter-duty applications or situations that require finesse and adaptability rather than raw strength. They are an essential part of a complete tarping toolkit, perfect for securing lighter poly tarps or covering equipment.

Fortress Rubber Straps: A Reliable Budget-Friendly Pick

Let’s be practical: you don’t always need a premium, professional-grade strap. For securing a tarp over the lawnmower for a few weeks or covering a small pile of bales overnight, a budget-friendly option like Fortress is often more than enough. They get the job done without breaking the bank.

The key is to understand what you’re buying. These straps are often made from natural rubber, which doesn’t have the same UV or temperature resistance as EPDM. Left out in the sun for a full season, they will degrade much faster. The hooks may also be a lighter gauge steel.

Use them for what they are: a cost-effective solution for short-term or less critical tasks. Buying a box to have on hand for general utility is a smart move. Just don’t rely on them to protect your entire winter’s hay supply through a blizzard. Know their limits, store them out of the sun, and they will serve you well.

Extending Strap Life: Proper Care and Storage Tips

The number one killer of any rubber strap is sunlight. UV radiation breaks down the rubber, making it brittle and weak. The single best thing you can do to extend the life of your straps is to store them in a dark, dry place like a shed cabinet, a toolbox, or even a five-gallon bucket with a lid.

Get in the habit of giving each strap a quick inspection before you use it. Look for small cracks, nicks, or areas where the color looks faded or chalky—these are signs of UV damage. Give the S-hook a tug to ensure it’s still firmly crimped and check that it hasn’t been bent out of shape from the last use. Catching a weak strap before it’s under tension can save you a world of trouble.

Finally, avoid the temptation to stretch a strap to its absolute maximum limit. A good rule of thumb is to never stretch a strap more than about 50% beyond its resting length. Consistently over-stretching a strap permanently damages its internal structure, drastically shortening its life and making it much more likely to snap unexpectedly. Choosing the next size up is always the safer bet.

In the end, there is no single "best" tarp strap, only the best one for the specific job in front of you. A smart farmer builds a collection over time: a bundle of reliable EPDM straps for daily work, a few heavy-duty ones for the main stack, and a handful of adjustable or budget options for odd jobs. By matching the tool to the task, you ensure your hay stays dry and your investment stays protected.
