Description

Southwire's Romex Brand SmartBox Boxes are unmatched in versatility in new work locations where you cannot swing a hammer, or where final wall surfaces are uncertain, like kitchens and baths. Interior mounting screws allow for depth adjustability to accommodate tile, paneling, and other specialty wall treatments. These boxes are unmatched in both new and old work applications because they are always mounted to a stud.
