The liquid-tight cord connector from Hubbell® Wiring Device-Kellems features the proprietary split-hinge Gotcha® ring that grips the conductor through the cord jacket. Factory-lubricated bushing provides even compression, ensures liquid-tight seal around cord, and minimizes tension on terminals. Machined metal cord connector is more durable and reliable than cast metal parts. Use zinc-plated steel where higher impact resistance and tensile strength are desired. UL Listed. CSA Certified.
