Assembly friendly. Independent of insertion into the panel, Lockit Strain Reliefs self-lock onto the cable. Thus, they may be pre-assembled offline for final assembly at a later time or remote location, for lower installed cost.
Lockit Strain Reliefs hold so well they pass the UL pullout test requirements with or without panel support.
Protects the lifeline of your electric/electronic products by absorbing the forces of push and pull that may be exerted on the flexible power cord. And, their rectangular design eliminates the possibility of part rotation under forces of twist.
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.
Standardize panel design. Fill unused lockit Strain Relief mounting holes with the Heyco Rectangular Plug
RP 115-130 (Part No. 1890).
Assemble Heyco Lockits™ 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.
