  • Assembly friendly! Independent of insertion into the panel, Lockit Strain Reliefs self-lock onto the cable. Preassemble "off line" for final assembly at a later time or remote location, for lower installed cost!
  • Lockit Strain Reliefs hold so well they pass the UL pull-out test requirements with or without panel support.
  • Protect the lifeline of your electric/electronic products by absorbing the forces of push and pull that may be exerted on the flexible power cord. Rectangular design eliminates the possibility of part rotation under forces of twist.
  • Installs easily with fingertip pressure into a standard round or "Double D" hole. No tools required even for hand assembly.
  • Lockit's three-finger design securely anchors into panels as thin as .032" (0,8 mm) and as thick as .157" (4,0 mm) for a neat, clean appearance.
  • Five locking steps accommodate a wide range of panel thicknesses.
  • Low profile head satisfies design aesthetics.
  • Assemble Heyco Lockits™ (excluding ST-201N) with a Lockit plier (Part No. 0020).
  • Heyco nylon strain reliefs are also available in Labkit #1. This handy compartmentalized box provides a working assortment for prototype use in design and engineering groups.
