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.
