Madison Electric MSBHZ Adjustable Depth Device Box, 3-3/4 in L, 3.82 in W, 1 -Gang, PVC, Gray

The original smart 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. Smart boxes are unmatched in both new or old work applications because they are always mounted to a stud.
