Abstract

Abstract A cable guard is provided for use in connection with a Ratchet Lever Drum Puller having a ratchet toothed wheel integrally cast with the drum, and having a reverse ring construction. The cable guard is provided from a single sheet of material which also assists in preserving the helical wind of the cable, and the cable guard cooperates with a cable guide to assist in securing the former, and to deter improper positioning of the dead end hook on the cable guide.
