WLL is the most the part may carry in service. Proof and breaking loads are test figures — never lift to them. Each load is shown in the unit the manufacturer rates the part in, and a size ships with the manufacturer’s test certificate.

This range is published with a breaking load only, not a working load limit. Tell us the duty before using it to lift, and we will confirm a rating or recommend a rated part.
