Abstract
Abstract A fastening device for an open-bottom recessed electric fixture housing equipped with circumferentially spaced mounting slots and a ceiling abutting flange or rim. Each fastening device comprises (1) a one piece adapter bracket (2) a complemental clip, and (3) a screw-threaded headed fastener which is adapted to be passed through a bolt hole in the ceiling and screwed into coacting screw-threaded holes provided thereof in oriented portions of the bracket and clip respectively. The adjacent upper ends of the bracket and clip have T-shaped anchoring tabs keyed one above the other in the associated slot. Tightening the screw with a screwdriver lifts the housing and clamps it securely in its given position.
