Abstract: A hardware display unit includes a front grid having a front matrix of openings, and a rear grid having a rear matrix of openings corresponding in position to the first matrix of openings. The front grid is positioned with respect to the rear grid such that corresponding pairs of openings in the front and rear matrices together define downward sloping bays for receiving hardware. The display unit further includes side brackets mounted to side edges of the front and rear grids, the side brackets extending behind the front and rear grids for attaching the display unit to a vertical supporting structure. The display unit further includes a cap mounted to the front and rear grids. The cap includes a substantially horizontal surface extending from the front and rear grids towards a vertical supporting structure to which the first and second side brackets are attached. An adapter unit allows smaller items to be loaded into the display unit.
