 | Heyco® Lockit™ Strain Relief Bushings
For Flat Cables - Rectangular Mounting Hole
US Patent No. 4913385- Assembly friendly. Independent of insertion into the panel, Lockit Strain Reliefs self-lock onto the cable. Thus, they may be preassembled offline for final assembly at a later time or remote location, for lower installed cost.
