Nilight Trailer Safety Chains G70 3/8" x 35" 2-Pack — 26,400 lb Break Strength, Clevis Snap Hooks

Nilight 2-pack of G70 3/8" x 35" trailer safety chains with clevis snap hooks are heavy-duty tow chains designed to provide a strong backup connection between trailer and tow vehicle, rated to a 26,400 lb break strength.

These safety chains are built for demanding towing tasks — from campers and utility trailers to boats and gooseneck setups. Each chain is heat-treated and strength-tested, and the included forged hooks feature safety clips to help prevent accidental uncoupling. They meet common towing practices for crossing chains beneath the coupler and attaching to receiver loops, delivering a reliable secondary link in case of hitch failure.

How strong are these chains and what do the ratings mean?

The chains are Grade 70 (G70) alloy, engineered for high tensile strength in towing applications. The manufacturer lists a combined break strength of 26,400 lbs for the set, with a working load limit around 6,600 lbs per chain; these numbers indicate the maximum and safe operational loads used for selection and matching to your towing system.

• Grade 70 alloy links heat-treated for durability
• 3/8" chain thickness, 35" length per chain
• 26400 lb combined break strength (manufacturer specification)
• Working load limit approx. 6,600 lbs per chain

How do I attach and use the Nilight safety chains properly?

Attach one chain to each trailer anchor point and connect the hooks to the tow vehicle receiver loops. Cross the chains under the trailer coupler so they form a cradle that helps control the tongue in case the hitch separates; secure clips on the clevis hooks keep connections from slipping loose.

• Use both chains and cross them under the coupler for correct safety geometry
• Insert removable zinc-plated pin and cotter when fitting chain retainer
• Hook clevis snap hooks to vehicle loops and close safety clips
• Check for proper length and slack before every trip

Are these chains compatible with trailers, RVs, boats, and gooseneck couplers?

Yes — the design and strength rating make these chains suitable for a wide range of towing setups including small to medium trailers, RVs, and boat trailers. For gooseneck couplers, confirm attachment points and local regulations; the chain can be used where appropriate anchor points and rated connectors exist.

• Useful for utility trailers, campers, boat trailers, and some gooseneck systems
• Forged clevis hooks provide secure, easy attachment
• Check vehicle and trailer manufacturer load recommendations before use
• Follow local towing laws that mandate safety chains

How do I maintain these chains to keep them safe and lasting?

Inspect chains and hooks before each trip for wear, corrosion, or deformation. Keep moving parts like the clevis pin and hook clips clean and lubricated lightly if needed, and replace any chain with visible damage rather than attempting repairs.

• Visual inspection for cracks, elongation, or severe rust
• Replace if links are bent, welded, or weakened
• Store dry and occasionally apply rust inhibitor to exposed metal
• Retain or replace zinc-plated pin and cotter for secure installation

Who is this for? Tow vehicle owners who haul trailers, boats, or RVs and need a robust secondary connection should consider these Nilight Grade 70 safety chains. They are aimed at drivers who require greater strength than basic chains provide, and who follow standard towing installation practices. Match these chains to the tow system’s rated capacities and local requirements to ensure proper, safe use.
