Abstract: A shelving system (10) is provided for displaying articles within partitioned areas defined by a partition (30). Partition (30) is engaged to both the shelf bottom wall (24) and rear wall (25) in a reversibly locking manner. Partition (30) comprises a plate (32) having a tab member (60) which engages the rear wall (24) of shelf (20) through a slotted opening (23). Plate (32) further comprises an angularly directed tab member (70) which engages the bottom wall (24) of shelf (20) through slotted opening (27). Angularly directed tab member (70) includes a camming surface (76) which acts to translate vertical forces to rear wall (24) for displacement thereof relative to bottom wall (24). The elastic displacement of rear wall (22) permits angularly directed tab (70) to pass through slotted opening (27) such that the front edge of slotted opening (27) engages detent (74) of the angularly directed tab member (70).
