Wedge-Lock Wire Rope End Fittings—For Lifting

Also known as open wedge sockets, these end fittings require only a torque wrench to install. To install, wrap the wire rope around the removable wedge before securing it inside the body. A wire rope clamp attached through the top hole in the wedge secures the short (dead) end.

Two additional holes at the bottom of the wedge can be used as a "go/no go" gauge to determine the proper rope size. The wire rope should pass through the "go" hole and not through the "no go" hole.

Warning: Fittings must match rope diameter and be installed correctly to obtain maximum holding power. Test all assemblies for required strength before use. Do not use with coated rope unless the coating is removed.
