High-Strength Grade 40/43 Chain—Not for Lifting

This chain is approximately 50% stronger than Grade 30 chain. Use it for binding loads, tie downs, and towing applications. It is stamped with the grade and manufacturer. When using fittings with chain, you must match the trade size and meet or exceed the chain’s grade.

Zinc-plated steel chain has good corrosion resistance. Galvanized steel chain has excellent corrosion resistance.
