Nilight Trailer Safety Chains — 2PCS 3/8" x 35" Grade 70 with Forged Clevis Snap Hooks

Nilight 2PCS 3/8" x 35" Grade 70 trailer safety chains with clevis snap hooks provide a high-strength backup connection for trailers, RVs, boats, and gooseneck couplers.

These two safety chains are built from heat-treated Grade 70 alloy steel and designed to meet demanding towing situations where a dependable secondary attachment is required. Each chain is a standard 3/8" link, 35 inches long, and ships with forged clevis snap hooks and zinc-plated removable pins, giving you both corrosion resistance and convenient installation. The assembly offers a combined breaking strength rating of up to 26,400 lbs (working load limit 6,600 lbs per chain), making it suitable for a wide range of towing rigs while complying with common safety practices.

How do these chains improve trailer safety during towing?

Safety chains act as a backup connection between trailer and tow vehicle if the primary hitch fails or becomes disconnected. Nilight Grade 70 chains are engineered to catch and control the trailer until you can stop safely, limiting trailer sway and separation risk.

• Grade 70 heat-treated alloy steel for predictable strength and durability
• Forged clevis snap hooks with safety clips keep hooks secured under load
• 35" length offers flexible routing around couplers and hitch receivers
• Crossing chains under the coupler creates a cradle that supports the tongue if disconnected

Will these chains fit my trailer, RV, or gooseneck setup?

These chains use the common 3/8" standard link size and 35" length, making them compatible with most light- and medium-duty trailers, RVs, and many gooseneck couplers. The clevis snap hooks accept typical hitch receiver safety loop openings and provide quick attachment.

• 3/8" link size matches industry-standard safety chain connections
• 35" length allows routing and crossing under the coupler as recommended
• Removable zinc-plated pin and cotter simplify hook replacement or pinning
• Forged hooks fit common safety chain loop sizes on trailers and receivers

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

Each chain is Grade 70 and heat-treated with a rated working load limit (WLL) of 6,600 lbs. The listed capacity of 26,400 lbs reflects the combined nominal breaking strength across both chains under static test conditions, while WLL indicates the safe everyday load guidance.

• Grade 70 alloy steel for high tensile performance
• Working Load Limit 6,600 lbs per chain — use rated WLL for safe planning
• 26,400 lbs nominal breaking strength across both chains under test
• Always cross chains and inspect for wear, deformation, or corrosion before use

How do I install and maintain Nilight safety chains?

Installation is straightforward: attach each chain to the trailer frame or coupler and to the tow vehicle's safety chain loops, crossing them beneath the coupler. Regular inspection and occasional cleaning will keep the chains functioning reliably.

• Cross chains under the coupler to form a cradle—and hook to receiver loops
• Use the zinc-plated removable pin for quick hook replacement or secure pinning
• Inspect for cracks, bent links, or excessive corrosion before every trip
• Store dry and consider light lubrication to reduce surface rust over time

Who is this for: Tow vehicle owners who want a robust, easy-to-install secondary connection for trailers, boats, campers, or gooseneck setups. These chains suit owners of light- to medium-duty trailers, RV travelers, boaters, and anyone who needs Grade 70 rated safety chains with quick-attach clevis snap hooks for dependable towing backup protection.
