The IB-3100 is a blank wall box that mounts into a 3-gang deep masonry back box. Shallower back boxes can be used depending on the depth of the controls and electronics that must be mounted behind the IB-3100. Behind the front door it’s .75” deep, providing your custom wall controls with a professional appearance. The IB-3100 comes with a camlock (Standard) or you can request a thumb latch (optional).
