A simplified drop celing room conversion is accomplished without, in any manner, disturbing the original ceiling of an office or room by providing integral, generally angle-shaped, longitudinally-extending structural members that are to be securely and fully mounted in an endwise-aligned relation on and about walls of the room at a desired lower ceiling height and, in such a manner as to fully and exclusively serve to support and carry a so-called drop ceiling. Each member has a horizontally-outwardly-extending upper shelf part for fully supporting and carrying cross-extending rail members that define open spaces therebetween with the sidewall-mounted supporting structural members, and which with the supporting members, are adapted to tilt-in receive dry wall ceiling panels in the spaces therebetween. The structural members are of a unique construction embodying a horizontally extending ceiling-receiving shelf part, an intermediate connecting tool-guiding part or bead, and a downwardly extending wall mounting vertical leg part. Each support member is self-sufficient in that the exposed underside of the upper shelf part is provided with a finish strip, and the bead has a slightly backwardly sloped and downwardly offset guide face to receive and accurately guide an edge portion of a tool blade therealong in such a manner as to spread a finishing compound, such as spackling, in a smoothly fully covering, and downwardly feathering-off relation over the exposed front face of the mounting foot part and its associated wall-securing elements, such as screws or nails that are carried thereby.
