The Cooper Wiring Devices 1212 is a heavy‑duty, commercial‑specification surface‑mount range receptacle built to deliver safe, stable, and reliable power for high‑amperage electric ranges and cooking appliances. Engineered with a rugged glass‑filled nylon housing and a corrosion‑resistant galvanized steel mounting strap, this 50‑amp, 125/250‑volt receptacle is designed for demanding environments where long‑term durability and strong electrical integrity are essential.

Featuring a 4‑wire grounding configuration and NEMA 14‑50R compatibility, the 1212 meets modern electrical code requirements for grounded range installations in residential, multifamily, and commercial settings. Its surface‑mount design offers flexible installation options where a recessed box is not available or where exposed mounting is preferred for accessibility, serviceability, or retrofit applications.
