An office accessory system for attachment to a wall-mounted load bar for suspension from a vertical surface includes an office accessory suitable for use in either a vertical or horizontal orientation and a pair of mounting brackets. The mounting brackets are attached to the load bar, and the office accessory has two opposite sides which cooperate with the mounting brackets to permit the accessory to be supported from the load bar in either its vertical or horizontal positions of use. When utilized to attach the accessory to the load bar, the mounting brackets are substantially hidden from view.
