Abstract
Abstract A plaster frame for mounting a lighting fixture in recessed fashion in a ceiling comprises a main body portion including a rectangular, planar member defining an aperture therein, the aperture being similarly dimensioned to the ceiling aperture in which the lighting fixture is to be mounted. Hanger bar brackets are integrally formed with the planar member at breakaway junctions along opposite, first sides of the planar member. The hanger bar brackets are adapted to receive hanger bars for mounting the plaster frame between spaced joists supporting the ceiling. Each hanger bar bracket is removable from the planar member by bending at the breakaway junctions. The hanger bar brackets are reattachable to the planar member along opposite, second sides thereof by means of bendable, spaced tabs formed on the brackets receivable in similarly spaced apertures defined in the planar member. The ability to relocate the hanger bar brackets permits the plaster frame to be oriented in two ways between the spaced ceiling joists. Complete removal of the hanger bar brackets permits insertion of the plaster frame through an aperture defined in an existing ceiling to provide support for a lighting fixture on the interior surface of the ceiling.
