Thomas Betts CDOW Steel Switch Box 1 Gang Old Construction

Product Description

The THOMAS BETTS CDOW is a single-gang steel electrical switch box designed for old construction retrofit installations. It provides a secure, code-ready housing for standard wall switches and receptacles in residential and light commercial wiring applications. The box measures 3 inches in height, 2 inches in width, and 2.5 inches in depth, making it compatible with standard single-gang cutout openings. A galvanized steel finish resists corrosion in typical indoor environments. Six pre-scored 0.5-inch knockouts provide flexible conduit or cable entry from multiple directions. UL listed under File E2969, confirming compliance with recognized safety standards for electrical enclosures.

This switch box is suited for retrofit and remodel work where new-work brackets are not practical. The old construction mount style allows installation into existing finished walls without removing drywall or plaster. Electricians use this box when replacing damaged boxes, adding outlets or switches in existing walls, or completing renovation projects where the framing is not exposed. The single-gang configuration accommodates one device, such as a toggle switch, decorator-style switch, or duplex receptacle with a standard cover plate.
