CURT Vinyl-Coated Trailer Safety Cables 43-7/8 in — 3/8 in Snap Hooks, 3,500 lb (2-Pack)

CURT 80136 are vinyl-coated trailer safety cables in a two-pack, 43-7/8 inches long, with 3/8-inch snap hooks and a 3,500 lb minimum break strength each.

These medium-duty safety cables are an alternative to traditional chains, built to help keep a trailer attached to the tow vehicle if the coupler separates. CURT designed this pair with a coiled, corrosion-resistant vinyl jacket and spring-loaded snap hooks so they stay quieter, easier to handle, and more secure over rough roads. They’re intended for common trailers and typical towing situations where a 3,500 lb minimum break strength per cable is appropriate.

How do these cables reduce noise and corrosion during towing?

The vinyl coating encases the steel cable to minimize metal-on-metal contact and block moisture, which cuts down rattling and rust. The coating also provides a smoother surface that’s more comfortable to grip and less likely to damage paint or wiring it contacts.

• Vinyl jacket reduces clatter and abrasion
• Protects steel core from salt and moisture
• Smoother handling when attaching or stowing cables

Are the snap hooks more reliable than S-hooks?

These cables use 3/8-inch snap hooks with a spring-loaded latch that stays closed under vibration, offering better retention than open S-hooks. The latching mechanism helps prevent accidental unhooking across bumps, making them a safer choice for many towing conditions.

• Spring-loaded latch resists bouncing open
• Pre-attached hooks for convenient hookup
• Designed for repeatable, secure connections

What towing capacity and trailer types suit these cables?

Each cable has a minimum break strength of 3,500 pounds, making the pair appropriate for medium-duty trailers—when used according to local regulations that typically require two safety cables. Always ensure each cable meets or exceeds the trailer’s gross weight and check your jurisdiction’s rules for safety chain alternatives.

• 3,500 lb minimum break strength per cable
• Recommended for standard utility, boat, and light equipment trailers
• Use two cables as a pair for proper safety redundancy

How long are they and how do coiled cables help on the road?

These safety cables measure 43-7/8 inches total length and are coiled to avoid ground drag while still extending when needed. The coiled design keeps cables compact when stored and reduces the chance of snagging or catching on roadway debris while towing.

• 43-7/8" overall length when relaxed
• Coiled form minimizes dragging and snag risk
• Extends under tension for functional clearance during turns

Who is this for? These CURT vinyl-coated safety cables suit owners of small to medium trailers—such as utility trailers, small boat trailers, or light equipment haulers—who want a quieter, rust-resistant alternative to bare chains. They’re a sensible choice for drivers who prefer snap-hook retention and a compact, coiled cable that’s easier to handle and stow. Always confirm the cables’ break strength meets or exceeds your trailer’s gross weight and follow local towing laws and safety recommendations when substituting cables for chains.
