Wiring Device-Kellems 73031202 Dust Tight Strain Relief Grip, 1/2 in Trade, 0.43 to 0.54 in Cable Openings, Aluminum, Electrogalvanized

Kellems® strain relief grips are designed to prevent tension from being transmitted to joints and terminals on electrical cord, cable and conduit. In most applications, a Kellems grip for strain relief is stronger than the cable itself and gives much greater security than the use of a fitting alone. Kellems Grips for strain relief help make electrical systems safer, and save money by minimizing downtime from costly electrical failure due to cable pull out. Kellems Grips also aid in compliance with the National Electric Code's terminal tension protection requirements.
