Abstract
Abstract A universal base for a bracket system comprises an open ended tubular member having a rectangular cross section. A T-shaped tongue projects at an angle from one end of the base back wall and the opposite or front wall is formed with at least two laterally spaced pairs of vertically spaced slots. With the tongue of one base engaged in the opening of a lipped channel member, the slots are simultaneously engageable by two shelf brackets or alternatively the upper open end of the base may accept a cabinet bracket that is laterally positionable over part of the width of the base.
