  • Assembly friendly! Independent of insertion into the panel, RDD Lockit™ Strain Reliefs self-lock onto the cable. Preassemble RDD Lockits off line for final assembly at a later time or remote location, for lower installed cost!
  • Installs easily with fingertip pressure into a standard round or "Double D" hole. No tools required even for hand assembly.
  • 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. "Double D" design eliminates the possibility of part rotation under forces of twist.
  • Multiple panel locking steps secure Lockit Strain Reliefs into a wide range of panel thicknesses for a flush, finished fit.
  • 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.
  • Fill blank/unused mounting holes with Heyco Double D Plugs.
