ABSTRACT:
A cover is provided for an electrical box, particularly when installed in an outside wall or in a ceiling, above which is a cooler space. The cover extends around all of the electrical box except the open face thereof and has a slanted flange which contacts and seals against the back surface of the wall or ceiling in which the box is mounted. The cover prevents cold air from entering the building through or around the box and heated air from escaping from the interior of the building. The cover also prevents water or moisture from entering the box from the outside. The cover has means for varying the distance the open face of the box extends beyond the slanted flange so as to accommodate walls or ceilings of different thicknesses. The cover also can be specifically designed to receive particular shapes of electrical boxes including a plurality of boxes.
