Garvin Industries Multi Device Switch Boxes are 2-1/8" and 2-1/2" deep and can be used in new construction or old work "cut in" applications on existing walls.  Their solid "one piece" construction means they will be securely mounted to wood or metal studs.  These boxes are used when multiple switches, receptacles or outlets are required in one location.  They come in two gang, three gang, and four gang styles, with or without labor saving installation brackets.  Old Work Boxes offer clips and plaster ears to securely mount them in existing walls.
