A housing for mounting electrical fixtures behind surfaces such as walls and ceilings, includes a surface flange and a plurality of pairs of axially directed slots in the side wall. When inserted in a hole in a ceiling or wall until the housing flange is flush with the wall or ceiling surface, a pair of spring elements are compressed and inserted through a pair of slots which allow the springs to bear against the slot and interior surface of the ceiling or wall to hold the flange flush.
