Abstract
A hanger for suspending armored cable from a vertical wire holds the cable to one side of the wire and includes a sharp edge that engages the wire on the side opposite the cable; a force is applied to press the sharp edge against the wire to prevent the hanger from slipping down along the wire. In other aspects, the hanger is supported from only a single location on the wire; the hanger includes a slot into which the wire may be slipped to reach a position where the wire is grasped by the hanger; and the cable holding portion of the hanger includes a rib to seat in the helical groove of the armored cable.
