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.
