Abstract: A shelving system including support units that are easily secured to the shelves without the need of special tools or forming unsightly holes in the shelving. Each support unit contains a U-shaped bracket that is connected to the bottom surface of one shelf by a hidden wood screw. A pair of end caps which are similarly connected to the top surface of an opposed shelf slidably receive the legs of the bracket therein to form a high strength unit capable of supporting the shelves in a spaced-apart relationship.
