When you need multiple, watertight and explosionproof receptacles—without a separate power run to each receptacle—count on U-Line® 20 Amp panel mounting plugs and receptacles. The receptacles are threaded for installation into approved enclosures with either threaded or non-threaded openings, allowing one run of wire and conduit to power as many receptacles as you need in a given area.

These receptacles feature the same twist-lock mechanism as our standard U-Line receptacles, producing an audible click to let you know the plug is locked in place and the receptacle is energized. Two models are available, with different threading styles:

ECHT is designed for use with 1-1/2" NPT tapered threads, such as in panelboards

ECH is designed to be used with 2" NPSM straight threads

Both styles are supplied with a steel locknut and neoprene sealing gasket assembly for use in settings where a threaded enclosure is not required.
