Abstract: The present invention relates to a device for sealing an electrical conduit comprising a tubular portion having a closed end and an open end. The device is formed of a resilient material. The closed end is adapted to have a wire or cable sealingly received therethrough. The outer surface of the tubular portion is of a diameter such that upon insertion of the tubular portion into the conduit, the outer surface of the tubular portion sealingly engages the inner surface of the conduit.

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.

Abstract: This invention consists of a transparent non-inflammable plastic container the purpose of which is to enclose an electrical outlet box to prevent air and water or moisture from entering into or passing through such box. The container is in the form of a rectangular box for use with rectangular outlet boxes, and is round for use with round or octagonal outlet boxes. Each of the containers is provided with a flange around the open rim of it, and said flange extends outwardly and at a small angle to the wall of the container.

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.
