Assembly friendly! Independent of insertion into the panel, the Ratcheting Strain Relief self-locks onto the cable. Thus, it may be preassembled offline for final assembly at a later time or remote location, for lower installed cost! Unique wire locking ratchet allows for generous wire range from .115" (2,9 mm) to .750" (19,1 mm). Can be used for one cable or multiple cables (round or flat wire). Installs easily with fingertip pressure into a standard round or Double D hole. Ratcheting Strain Relief can be easily removed by inserting standard snap ring pliers with .040" tips (Heyco PN 0054) into the two holes on the part (see drawing) and spreading part open. Ideal solution for managing internal wire bundles such as wire harnesses. PN 1280 UL Recognized for multiple cables/conductors. Consult Heyco for other wire types and sizes.
