BACKBOXES
Backboxes and cabinets (without their doors) are usually delivered prior to other system components. Make sure
that the backboxes are installed in the proper location by referring to the building’s architectural drawings. Some
boxes will have to be modified in accordance with instructions in this section. (See Figure 20 for backbox sizes.)
Backboxes whose mounting positions are not obvious contain a label indicating their mounting position. When one
of these labels is in the box, mount the box with the word “TOP” in the uppermost position.
Some backboxes will be installed side by side. Make sure you allow at least 2 inches between the backboxes to
leave enough room for the doors to swing open.
Note: Instructions for mounting doors onto backboxes are provided with the door’s mounting hardware.
