Many companies make their own version of a self-locking safety hook, and most perform just fine. But Yoke went a step further with this safety grip design. The handle on the backside of the hook is not just for handling, but more so for worker safety. It allows the user to grab hold of the hook and manipulate the safety trigger (which allows the self-closing latch to open and close) without putting his or her hand inside the load-bearing area of the hook. This helps to avoid hand injuries that are all too common in rigging. Made from Grade 100 alloy steel, proof-tested and magnetic particle inspected. Eye fitting on top of hook means you can use this with chain, wire rope or any other common sling material.
