Ceiling fixture firestop
A system for use with a ceiling fixture, a portion of which projects though an opening in a ceiling wall, for assisting in preventing spread of fire through the opening. The system has a metal collar for lining the opening. The metal collar has an upper rim overlying a top surface of the ceiling wall at the opening, a middle section facing an inner edge of the ceiling wall at the opening and a lower rim underlying a bottom surface of the ceiling wall at the opening. The system also has an intumescent ring for surrounding the projecting portion of the fixture so as to be interposed between the metal collar and the projecting portion of the fixture.
