A vertically stabilized shelf bracket assembly having at least two support strips on which a plurality of shelf brackets are mounted. The shelving is stabilized in several ways. First, the brackets are provided with a shelf engaging recess. The recess is either designed to provide a tight fit for the shelf, or the recess is provided with a shim for tightening the fit. Second, the brackets are provided with a vertical member which engages the shelves. Preferably, the recess and the vertical member will engage the shelf at opposite ends of the shelf, securing the shelf to the bracket. When the shelf is attached to multiple brackets, the shelf will be prevented from pivoting on the bracket. The shelves can be further stabilized by securing the brackets against vertical displacement. This can be accomplished by securing the shelf brackets to the support strip with a locking pin. With the locking pin in place, the shelf bracket cannot be moved upward. Another way of securing the brackets is to provide a vertical stabilizer, comprising an elongated member, preferably of steel or aluminum, having an arm extending perpendicularly therefrom. The arm will fit tightly into a slot in a support strip. When the arm is in place, the elongated member will be positioned over and in contact with the base of the shelf bracket, so that the bracket cannot be moved upward. The vertical stabilizer will be held in place by the cover which fits over the support strips.
