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.
