High-Strength Grade 100 Chain—For Lifting
This chain is approximately 25% stronger than Grade 80 chain. It's 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.
Zinc-plated steel chain has good corrosion resistance.
Warning: Never use to lift people or items over people.

Wear Gauge

Gauge measures the maximum allowable wear tolerances on links of Grade 80 and Grade 100 steel chain, as required by OSHA. If the gauge can be inserted over any part of the link, the chain should be taken out of service.
