Wiring Device-Kellems 073031215 Dust Tight Light Duty Standard Strain Relief Wide Range Cord Connector, 2-1/2 in Trade, 2 to 2.45 in Cable Openings, Aluminum/Steel, Galvanized

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.
