Review on Camco Residential Screw Heater Element Rough Plumbing by William Anacker

This outlet never quite fitted the Camco heater it was designed to work with. When I applied torque to it, the element would not disengage, but the stamped metal bushing would expand (back to round) causing it to slip completely and causing injury to the joints! it only cost $7, not sure if it's worth the time to return it! Do yourself a favor and buy a real socket that can be used with a switch or ratchet and is not a cheap POS. like this!
