a surrounding wall integrally joined to an outer periphery of the outer wall and extending substantially normal to the outer wall; a barrier wall integrally joined to an inner periphery of the outer wall at an edge of the outer opening and extending substantially normal to the outer wall, the barrier wall forming an inner opening opposite the outer opening to meet the outlet box; and an attaching flange integrally joined to an inner end of the surrounding wall for being placed against the building wall, the attaching flange being a continuous flange about an exterior periphery of the surrounding wall. ## Claims ### Claim 1 A cover for an outlet box mounted in a building wall, comprising: an outer wall with an outer opening formed in the outer wall; a surrounding wall integrally joined to an outer periphery of the outer wall and extending substantially normal to the outer wall; an L-shaped barrier wall integrally joined to an inner periphery of the outer wall at an edge of the outer opening and extending substantially normal to the outer wall, the barrier wall forming an inner opening opposite the outer opening to meet the outlet box, a portion of the barrier wall extending toward the plane of the inner opening; and an attaching flange integrally joined to an inner end of the surrounding wall for being placed against the building wall, the attaching flange being a continuous flange about an exterior periphery of the surrounding wall. ### Claim 2 (depends on 1) The cover of claim 1 wherein the cover is unitary and made of plastic. ### Claim 3 (depends on 1) The cover of claim 1 wherein the surrounding wall and the barrier wall are of substantially equal height. ### Claim 4 (depends on 1) The cover of claim 1 wherein the outer wall and the attaching flange are parallel. ### Claim 5 (depends on 1) The cover of claim 1 wherein the shape of the inner opening is selected from the group of shapes consisting of round, rectangular, and square. ### Claim 6 (depends on 1) The cover of claim 1 wherein the barrier wall comprises a round portion and a rectangular portion. ### Claim 7 (depends on 1) The cover of claim 1 wherein the outer wall has a removable opening panel across the outer opening. ### Claim 8 (depends on 7) The cover of claim 7 wherein the removable opening panel forms a cutting aperture. ### Claim 9 (depends on 1) The cover of claim 1 further comprising a trim ring, the trim ring having a ring wall and ring extending flange substantially normal to the ring wall, wherein the ring wall is slideable about the surrounding wall. ### Claim 10 (depends on 9) The cover of claim 9 wherein the ring wall and the surrounding wall have complementary ridges and grooves. ### Claim 11 (depends on 10) The cover of claim 10 wherein the grooves associated with one of the ridges are spaced apart to provide a first distance between the ring extending flange and the attaching flange when a first groove is locked on the one of the ridges and a second distance between the ring extending flange and the attaching flange when a second groove is locked on the one of the ridges. ### Claim 12 (depends on 9) The cover of claim 9 wherein the ring extending flange is a first ring extending flange, and the trim ring further comprises a second ring extending flange substantially normal to the ring wall and on an end of the ring wall opposite the first ring extending flange. ### Claim 13 A system of an outlet box mounted in a building wall, the outlet box having a front opening and the building wall being covered with siding, comprising: an outer wall with an outer opening formed in the outer wall; a surrounding wall integrally joined to an outer periphery of the outer wall and extending substantially normal to the outer wall; an L-shaped barrier wall integrally joined to an inner periphery of the outer wall at an edge of the outer opening and extending substantially normal to the outer wall, the barrier wall forming an inner opening opposite the outer opening to meet the outlet box, a portion of the barrier wall extending toward the plane of the inner opening; and an attaching flange integrally joined to an inner end of the surrounding wall for being placed against the building wall, the attaching flange being a continuous flange about an exterior periphery of the surrounding wall; wherein the siding overlaps the attaching flange. ### Claim 14 (depends on 13) The system of claim 13 wherein the barrier wall comprises a round portion and a rectangular portion. ### Claim 15 (depends on 13) The system of claim 13 wherein the outer wall has a removable opening panel across the outer opening. ### Claim 16 (depends on 15) The system of claim 15 wherein the removable opening panel forms a cutting aperture. ### Claim 17 (depends on 13) The system of claim 13 further comprising a trim ring, the trim ring having a ring wall and ring extending flange substantially normal to the ring wall, wherein the ring wall is slideable about the surrounding wall, wherein the siding is disposed between the ring extending flange and the attaching flange.
