HANDLE EXTENSION 6' CC-289. The Kraft Tool's aluminum knob extension handle is lightweight, easy to handle, and provides space for multiple handle accessories. Comes with an inset design to create a gusset where the straps meet and securely attach them to other straps and brackets. Its dual-button clip attached to each handle helps it connect to other handles or brackets, and it can also be attached to threaded brackets or clevis brackets with an adapter.
