A display rack has a base which may be mounted on a wall. The base has an elongate slot having a retracted end, an extended end opposite the retracted end, a first groove and a second groove. The first groove is positioned between the retracted position and the second groove. The display rack has a tray with a fin movable within the elongate slot as the tray slides along the base between a retracted position, and an extended position. The fin may pass through the first groove, but not the second groove.
