ABSTRACT:
A flanged outlet, such as an electrical outlet box is provided for installation on an exterior wall of a building. The outlet has laterally enclosing walls the interior surfaces of which define an opening therewithin. The opening faces outwardly away from the exterior building wall. The box has a unitary integrally formed flat flange that extends laterally from the exterior surfaces of all of the walls about the entire perimeter of the outwardly facing opening. The flange is located behind the outlet opening. The flanged outlet can be employed in conjunction with upper and lower sheets of waterproof material, such as the waterproof black paper that is used to provide a moisture barrier in conventional building construction. A lower sheet of waterproof material resides between the flange of the outlet and an outwardly facing building surface and extends downwardly from beneath the outwardly facing opening of the outlet. An upper sheet of waterproof material is fastened to the outwardly facing building surface above the outlet flange. Moisture is thereby carried down the outer surfaces of the waterproofing sheets, and cannot penetrate to the interior of the building through openings defined therein to accommodate the outlet of the invention.
