ABSTRACT:
An outlet assembly for a vacuum cleaning system includes a face plate for mounting on the exterior surface of a building wall, an annular inlet bushing or socket open from the face plate and extending through the building wall and a back plate positioned adjacent the interior surface of the building wall and opposite the face plate and with the inlet bushing extending therethrough. The inlet bushing connects to a vacuum conduit from the vacuum cleaning system for flow of air therethrough. A seal fitting member is positioned generally between the building wall and the back plate and sleeved about the inlet bushing. A resilient seal therein engages the outer surface of the inlet bushing in air-tight relationship and a flange portion engages with the open end of the vacuum conduit and secures the vacuum conduit to the inlet bushing. The back plate has opposite sides with spaced flange portions extending perpendicularly therefrom and during emplacement of the outlet assembly in a building wall, the back plate is reversible to position the end of the vacuum conduit either closely against the wall or spaced therefrom a distance to accommodate variations in building wall thickness.
