A building entrance protector assembly includes a building entrance protector housing having an opening. The housing includes a plurality of concentric cylindrical side walls around the opening. Each side wall at least partly overlies another one of the side walls. At least one annular surface is provided at an end of the side walls distal from the flange. The distance between the flange and each distal (annular or disk shaped) surface increases monotonically from an outermost annular surface to an innermost annular or circular surface. Each annular surface is located at a respectively different distance from the flange. Each side wall is connected to an adjacent side wall by one of the annular surfaces. One or more of the inner side walls may be cut away to accommodate a variety of cable sizes. A cable passes through an innermost one of the side walls. A heat shrink tubing secures the cable to the adapter. The heat shrink tubing is adhered to the cable and the outermost side wall. The innermost side wall has approximately the same diameter as the cable. Optionally, the housing has an adapter mounted on it. The adapter includes the side walls and the annular surface. The adapter includes a mounting flange for mounting the adapter to the housing. Alternatively, the side walls, annular surfaces and distal circular surface may be formed integrally as a part of the end cap of the housing.
