Standard color black. Consult Heyco for white and other colors.
*Designed for cast or other mounting holes with rounded edges.

• 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!
• Install 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's automated Pre-Assembly Equipment speeds assembly of the RDD onto the cable and thus lowers costs while greatly reducing risk of carpal tunnel syndrome.
• Consult Heyco for other wire types and sizes.
• Corresponding Mounting Hole Plugs can be used to fill blank/unused Mounting Holes and thus allow for a single panel design for multiple applications.
