TKK 36 Inch Trailer Safety Chain 3/8 in Clevis Snap Hook - Durable

Our review of the TKK 36 Inch Trailer Safety Chain finds it best suited for owners of medium to heavy trailers who need a dependable backup connection between trailer and tow vehicle. The clear standout is the use of grade 80 chain, which offers high tensile strength and wear resistance so the chain is more likely to hold rather than separate under extreme stress. In practice this set of two 36 in chains with clevis snap hooks gives a straightforward, durable safety solution for towing boats, utility trailers, and equipment trailers where corrosion resistance and a known working load limit matter.

Key Features

• Grade 80 construction: Provides superior tensile strength and wear resistance to reduce the risk of complete separation if the primary hitch fails.
• 7,100 lb working load limit: Each 3/8 in chain is rated to handle substantial loads when used within the marked limits, giving confidence on heavier trailers.
• Heat-treated and strength-tested: Standard links are heat-treated for toughness and tested for consistent performance in towing applications.
• Galvanized surface: The zinc-plated finish improves corrosion resistance so the chains stay serviceable in wet and salty conditions.
• Removable chain retainer pin: A zinc-plated removable pin on the retainer makes installation and replacement convenient during maintenance or upgrades.

Who It's For

This kit is aimed at trailer owners, small fleet operators, and boat owners who tow medium to heavy loads and want a robust, inspection-ready safety chain. The set is particularly useful for those who prefer metal-to-metal safety features and who value a marked working load limit for compliance with roadside inspections.

Those who should look elsewhere include drivers towing very light loads who need lighter, more compact hardware, or buyers who require specialized fittings not included here (for example, different hook styles or custom lengths). If you need integrated quick-release systems or non-metal alternatives, this product is not intended for that use.

Pros & Cons

Pros

• High-strength grade 80 chain offers dependable tensile performance under load.
• Clearly marked working load limit of 7,100 lb helps ensure proper matching to trailer weight.
• Galvanized finish and heat treatment improve durability and reduce corrosion risk.

Cons

• The 36 in fixed length may require modification for some installations and adds weight compared with lighter alternatives.
• Only one hook style (3/8 in clevis snap hook) is included, so other attachment preferences require additional parts.
