Switch Box for EMT One Gang 3-1/2" Deep, 25 Pak

These one gang non-gangable 3-1/2in deep old work switch boxes are used in hollow walls when a single electrical or electronic device is required in one location. 1/2in and 3/4in concentric knockouts allow versatile conduit and cable installations. Plaster ears and snap on clips tightly secure the box to any finished surface. Extra deep 3-1/2in box is great for large devices or extra wire capacity. Standard finished wall plates cover the entire unit for a clean finished look on any interior wall
