ABSTRACT:
A bracket for cantilever mounting of flat shelf plates has a vertical member with upper and lower spaced projections. A pressure housing is mounted on the underside of the upper projection, and a pressure plate is movably mounted in such underside. Pressure is applied to the pressure plate by a ball bearing mounted in the pressure housing for up and down movement. A set screw is mounted in the pressure housing and positioned to apply downward pressure on the ball bearing and on the pressure plate, whereby a flat shelf member may be inserted between the upper and lower projections and locked in place with the set screw to provide cantilever support at one end of the shelf member.
