7 Best Tow Safety Cables

Imagine cruising down a mountain pass when you hear a loud bang, and your rearview mirror suddenly shows your towed car drifting into the other lane. This nightmare scenario is precisely what flat tow safety cables are designed to prevent. They are the non-negotiable, last-resort connection between your RV and your toad, and choosing the right set is one of the most critical safety decisions you’ll make.

The Critical Role of Flat Tow Safety Cables

Safety cables are your rig’s seatbelt. In the event of a catastrophic tow bar or hitch failure, these two lengths of steel are the only things stopping your multi-thousand-pound vehicle from becoming an unguided missile on the highway. It’s not just a good idea; it’s legally required in virtually every state and province.

There are two primary styles you’ll encounter: coiled and straight. Coiled cables, like an old telephone cord, expand and contract as you turn, which keeps them neatly suspended off the pavement. Straight cables offer a direct, no-fuss connection but require careful length management to prevent them from dragging or binding up in a tight turn.

The choice often comes down to personal preference and your specific setup. Coiled cables are popular for their "set it and forget it" nature, while some seasoned towers prefer the simplicity and direct link of straight cables. Regardless of style, the most important factors are the weight rating—which must exceed the gross weight of your towed vehicle—and the quality of the construction.

Blue Ox Coiled Safety Cables: Top Nomad Pick

When you see a seasoned RVer hooking up their toad, there’s a good chance you’ll spot the distinctive blue spiral of Blue Ox cables. This brand has earned a rock-solid reputation in the community for a reason: their gear is reliable, well-engineered, and built to last through countless hookup cycles. They are a cornerstone of many integrated towing systems.

Blue Ox cables are typically vinyl-coated, which is a small feature with a big impact. It protects your tow bar and vehicle chassis from getting scratched and chipped during connection and travel. The coiled design keeps them from dragging on the ground, preventing premature wear and tear. Most sets come with high-quality, spring-loaded safety latches on the hooks, which are easy to operate even on a cold morning with stiff fingers.

You’re paying for peace of mind and system integration here. If you already own a Blue Ox tow bar, their safety cables are designed to work seamlessly with it. For many nomads, the slightly higher price is a small investment for the confidence that comes from using a proven, top-tier product that simply works every single time.

Roadmaster Straight Cables: For Direct Connections

Roadmaster is another giant in the towing world, and their straight safety cables are a favorite among those who prefer a direct, no-slack connection. The philosophy here is simplicity and strength. A straight cable provides a clear, unambiguous link between the RV and the towed vehicle’s baseplate.

The primary advantage of a straight cable is the lack of stored energy. Unlike a coiled cable that can spring and recoil, a straight cable just goes taut in an emergency. Some users find this more predictable. Roadmaster’s cables are aircraft-grade steel, usually galvanized or vinyl-coated for longevity, and feature robust, forged steel hooks or heavy-duty quick-links for attachment.

The key to using straight cables effectively is getting the length just right. You need enough slack to allow for sharp turns without binding, but not so much that they drag on the pavement during normal driving. This often means twisting them a few times around the tow bar arms to take up excess length—a simple but crucial step for a safe and quiet ride.

CURT Coiled Safety Cables: The Accessible Option

Sometimes, the best piece of gear is the one you can get your hands on right now. CURT is one of the most widely available towing brands, found in auto parts stores, big-box retailers, and online, making them an incredibly accessible option for nomads who might need a replacement on the road.

Don’t mistake accessibility for low quality. CURT produces solid, dependable safety cables that meet or exceed all safety standards. Their coiled cables are a popular choice, offering a great balance of performance and value. They come in various weight ratings, from light-duty 5,000-pound sets to heavy-duty 10,000-pound versions, ensuring a proper match for nearly any towed vehicle.

While they may not have the same premium finish or brand cachet as a Blue Ox or Roadmaster, CURT cables are workhorses. They provide a reliable, safe connection at a price point that’s hard to argue with. For the full-timer on a budget or anyone who values easy availability, CURT is an excellent and practical choice.

Demco Commander II Safety Cables: Built Tough

If your towing philosophy is "overbuilt is underrated," then Demco is a brand you need to know. Known for their rugged tow bars like the Commander II, Demco’s safety cables are engineered with the same heavy-duty mindset. These are the cables for people towing heavy Jeeps, trucks, or anyone who simply wants the most robust connection possible.

Demco cables often feature a higher-than-average weight rating and are constructed from vinyl-coated, aircraft-type galvanized steel. The focus is on durability and absolute strength. They are designed as an integral part of the Demco towing system, ensuring perfect compatibility and function with their tow bars and baseplates.

Choosing Demco is about investing in a system built for the long haul and the toughest conditions. The components feel substantial in your hands, and the connections are positive and secure. It’s a bit like choosing a commercial-grade tool over a residential one—you know it’s designed to handle more than you’ll likely ever throw at it.

NSA RV Products Cables: Integrated System Choice

NSA RV Products is best known for its innovative ReadyBrake and ReadyBrute Elite tow bar systems, which cleverly integrate a supplemental braking system directly into the tow bar itself. Their safety cables are designed with this same ethos of smart integration. Choosing their cables means you’re getting a component specifically designed to work within that ecosystem.

This is a huge advantage for anyone building a towing setup from scratch. When your tow bar, braking system, and safety cables all come from the same manufacturer, you eliminate the guesswork. You know the lengths are correct, the connection points are compatible, and the whole system has been tested to work together as one unit.

NSA’s cables are high-quality, typically coiled and vinyl-coated, and meet all the necessary safety standards. The real value, however, is in the system-based approach. For nomads who appreciate elegant engineering and a simplified hookup process, opting for the full NSA package, including their safety cables, is a very smart move.

Reese Towpower Safety Cables: Simple & Secure

Reese is one of the oldest and most trusted names in the towing industry. They built their reputation on no-nonsense, reliable hardware, and their safety cables are a perfect example of this. You won’t find a lot of fancy features here, just solid steel and secure hooks designed to do one job and do it well.

Reese offers a variety of both straight and coiled cables, often with a durable zinc plating instead of a vinyl coating. They are simple, strong, and affordable. The S-hooks typically come with a wire keeper that snaps shut, providing a secure connection that’s easy to inspect at a glance.

This is a great option for the pragmatic RVer. If you don’t need the system integration of a Blue Ox or the overbuilt nature of a Demco, Reese provides a perfectly safe and reliable connection that has been trusted by towers for decades. They are a testament to the idea that sometimes, the simplest solution is the best one.

Hopkins Towing Solutions: A Reliable Alternative

Hopkins is a major player in the towing world, especially known for their wiring and lighting kits, but they also produce a solid line of safety cables. Like CURT, they are widely available in automotive and general retail stores, making them a convenient and reliable choice when you’re on the move.

Hopkins offers a range of cables to fit different needs, including coiled and straight versions with various weight ratings. Their products are a dependable middle-ground, offering good quality construction and materials without the premium price tag of the specialized RV brands. They are a practical, get-the-job-done solution.

Think of Hopkins as a trusted alternative when your first choice isn’t available. You can be confident that their cables meet all safety requirements and will provide a secure link for your toad. For many nomads, having a reliable and easily sourced brand like Hopkins in their back pocket provides valuable peace of mind on the road.

Ultimately, the best brand of safety cable is less important than the principles behind them: ensure the weight rating is sufficient for your vehicle, choose a style that works for your setup, and inspect them for frays or damage before every single trip. Your safety cables are your ultimate backup plan; treat them with the respect that role deserves.
