Abstract: An adjustable shelving system having a pair of spaced uprights, each having a pair of spaced columns defining a plurality of mounting apertures which are adapted to receive fasteners securing brackets to the uprights, the brackets, in turn, supporting one or more shelves, each of which is provided with storing grooves for receiving storing units in their upright positions. Each bracket is provided with a pair of spaced slots angularly disposed with respect to a horizontal, one of the slots having an upper wall provided with indentations serving as a ratchet in conjunction with a fastener. The number of indentations that is selected determines incremental vertical movements of adjustability for the shelf. The lower edge of the bracket is provided with an upwardly facing flange which is adapted to receive a downward facing flange of the shelf.
