Tangle-Resistant Grade 30 Chain—Not for Lifting

This is the strongest tangle-resistant chain we offer. Shorter links make it easier to coil and less likely to knot. It is heat treated and 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.

Galvanized steel chain has excellent corrosion resistance.

Medium Duty Hammer-Close Connecting Links—Not for Lifting

Drive the end through the eye using a ball peen hammer and then weld or flatten the extended end to close. Also known as cold shuts, these links are an economical option to join chain links and attach fittings. They must be completely closed to perform at capacity. Never reuse links after they've been closed.

Zinc-plated steel links are mildly corrosion resistant.
