The wall boxes come with all necessary hardware to mount in new or old construction. They can be mounted in any direction, permitting the door to open up, down, right or left. There are two size boxes in two depths available. One will handle a standard three gang plate and the larger box will handle a standard four gang plate. The appropriate blank plate is supplied with each model. A key lock built into the design as well as a push-to open retention latch are included.
