ABSTRACT:
A cable protector for insertion into the open end of a duct or conduit for preventing a cable pulled therethrough from being damaged by the edges of the duct or conduit. The cable protector has a substantially C-shaped cross-section and includes a turned-over lip which encapsulates the end of the duct and prevents the cable protector from being pulled into the duct or conduit. A groove at the juncture of the lip and a curved transitional portion facilitates folding of the cable protector to allow insertion thereof into a variety of sizes of ducts or conduits. Ribs located on the external surface of the body of the cable protector ensures a substantially tubular configuration of the protector after its diameter has been reduced to fit into the intended duct or conduit. The inside surface of the cable protector may be textured to minimize friction.
