Quality grade 100 European fittings from KWB, a Pewag company. The Signal violet color allows for easy identification while in use. These are often used as chain shorteners on chain slings. The safety pin is designed to help lock the chain in place once it is set. A reduction of load capacity is not required due to the 4-fold safety cradle design. The eye style attachment allows this hook to be attached to different sling types and not just chain.
