One Gang Device Box - 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. They are unmatched in old or retrofit work applications because they are always mounted to a stud. Before Smart Box all other manufacturers hung their cut boxes on flimsy 3/8 or 1/2 sheet rock; or even worse lathe and plaster. Our Original Smart Boxes are unmatched in adjustability; as they are molded entirely of 1 piece with no moving parts to break or lose.
