Bushings anchored in cavities in the rear edge of a shelf to allow the shelf to be mounted horizontally flush against a wall with the bushings concealed, wherein screw heads projecting from the wall fit into seats in the bushings which resist straight-line horizontal displacement of the bushings from the screw heads but allow removal by lifting of the shelf so that the screw heads are released from the seats, and wherein a glue-filled annular groove or backwardly bent fins are formed on the exterior of the bushing to anchor the bushing in the cavity.
