Abstract
Preventing air leakage in a recessed lighting fixture. A plaster frame extends between hanger bars fastened to ceiling supports or joists. The plaster frame includes an aperture sized to receive a can. The can includes a pair of slots. A pair of retention springs are coupled to the plaster frame, on opposite sides of the aperture. Each retention spring is associated with one of the slots of the can. Each retention spring includes a base member and an elongated engaging member extending from an end of the base member. The elongated engaging member has a surface that has a contour corresponding to an outer profile of the can, proximate the slot. For example, a radius of curvature of the surface can correspond to a radius of curvature of the can. Thus, the retention springs engage the can in a substantially air-tight manner.
