ABSTRACT:
A cover is provided for an electrical box with a fastening flange, particularly when the box is installed in an outside wall or ceiling, back of which is a cooler space. The cover extends around all of the electrical box except the open face, with the fastening flange extending through the cover in an air and moisture tight relationship. The cover has a slanted, thin-wall flange which contacts and seals against the back surface of the wall or ceiling panel 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 electrical box and the cover are handled and installed as one unit to minimize extra labor. Preferably, the cover is molded on the box with portions spaced from the box where knockout plugs for wires are located.
