A clevis shortening hook is a specific type of hook used in chain slings for lifting and rigging applications. This type of hook is designed to provide a way to shorten the length of a chain sling while maintaining a secure connection to a load or an anchor point. It is particularly useful when you need to adjust the working length of the chain sling to accommodate various load sizes or achieve the desired angle for a safe and efficient lift.
Clevis shortening hooks are an alternative to grab hooks and are used to enable adjustment of the chain sling leg length. The shortening hook design is such that stresses on the chain are reduced as the chain is loaded "in-line" and not across the link as is the case with a grab hook.
