The OATEY COMPANY 38120 is a plain washing machine outlet box designed to provide a clean, recessed wall-mounted termination point for supply and waste drain connections in laundry installations. Built from high-impact polystyrene, this no-valve box recesses supply valve and waste drain connections into the wall cavity, reducing the finished footprint and keeping connections protected behind the appliance. It measures 3.5 inches long by 6.1 inches wide by 10.9 inches tall. Licensed plumbers and experienced installers use this box in new construction and remodel work where a flush, space-saving laundry rough-in is required.
The 38120 is suited for both residential and commercial applications that require supply valves and a waste drain recessed into the wall. Its compact profile allows it to fit in tight stud-bay spaces, making it practical for laundry closets, stacked washer installations, and utility rooms with limited wall depth. Because it ships without valves, the installer selects and installs the appropriate shut-off valves separately, allowing flexibility for the specific supply configuration required on the job.
Designed as an OEM-style recessed outlet box for standard residential and commercial washing machine installations requiring supply valve and waste drain connections recessed into the wall.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply to the work area before beginning rough-in. Secure the box to the framing per manufacturer instructions before closing the wall. Valves are not included and must be installed separately before the system is pressurized and inspected.
