The Double D Lockit strain-relief bushing is designed to fit into standard Double D openings. Flat sides at both ends of the bushing prevent the Lockit from turning in the opening. This protects current-carrying wires from twisting and from other natural or inadvertent stresses that can cause electrical failure.

Double D Lockit easily snaps into place without need for any tools, adding to installer comfort and safety while reducing assembly time and cost. The Double D Lockit strain-relief has a five-step locking mechanism unique to Heyco, covering chassis ranges to 0.125-inches thick. Sizes are available to fit cords ranging from 0.220- to 0.430-inch diameters.

Double D Lockit locks into place directly onto cords without need for chassis insertion, allowing it to be preassembled onto cords at the shop or jobsite, for additional time and cost efficiency.

Construction & Finishes: Double D Lockit strain-relief bushings are precision-molded in Heyco's own state-of-the-art U.S. plant of high-impact Type 6/6 nylon. Bushings have a flammability classification of UL 94V-2 and can withstand temperatures up to 125°C. An array of standard colors, and custom matches, are available.
