Care, safety, and maintenance
To maximize safety and lifespan, inspect the chain before each use for elongation, cracks, corrosion, or bent links. Do not exceed the 3,900 lb WLL and ensure you pair the chain with rated hooks, slings, and anchors. Store in the provided bucket in a dry environment to prevent corrosion, and avoid dragging or dropping the chain to preserve link integrity. If any sign of damage is detected, retire the chain from service and replace promptly.
