This type of rigging hook is used all over. It is popular for overhead lifting, but you will also find it on winch lines, hoists, towing straps and other such devices. We often attach them to wire rope slings to make lifting bridles for customers. They are easy to use and easy to attach with a simple Rigging Shackle. The biggest difference between these hooks and standard eye hoist hooks is that the upper bail on this hook swivels, which makes it easier to position prior to loading (for hooks that position under load, check out the Crosby S-3322B Swivel Anti-Friction Bearing Swivel Hooks). Made from alloy steel. Safety latches included and replacement latches are available. Factory certificates are available upon request.
