  • Assembly friendly!  Independent of insertion into the panel, the Ratcheting Strain Relief self-locks onto the cable. Thus, it may be pre-assembled offline for final assembly at a later time or remote location, for lower installed cost.
  • Unique wire locking ratchet allows for a generous wire range from .115" to .750" (2,9 mm to 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 Part ) into the two holes on the part and spreading part open.
  • Ideal solution for managing internal wire bundles wuch as wire harnesses.
  • PN 1280 UL Recognized for multiple cables/conductors.
  • Fill blank/unused mounting holes with Heyco Double D Plugs.
