ABSTRACT:
One end of an elongated beaded chain is secured in a screw base with a spring loaded connection. The chain extends downward through a central opening in a cover and in a reflector. The opening in the reflector includes a locking slot into which the chain can be placed. After the screw base is threaded into a conventional socket, the chain is passed through the opening as the reflector is drawn up into the opening for the existing recessed fixture. The fixture includes a trim ring which is placed against the ceiling which surrounds the recessed fixture. The chain is then pulled down against the spring in the screw base, pulled to the side into engagement with the slot portion of the opening, and released. The spring pulls upwardly on the chain and seats the new fixture snugly against the ceiling. The spring provides a small amount of flexibility to adjust for expansion and contraction due to temperature, normal structural vibrations, and the like.
