Abstract: The storage and display rack includes four like panel structures (A) and a plurality of dividers (B) mounted between opposite panel structures. Each panel structure includes an outer wall (30) from which a face portion (32), a rear edge portion (34), a tongue portion (36), a tongue receiving portion (38), and a plurality of rib pairs (40, 42, 44, 46, 48, 50, 60, 62) project inward. The face portion has breakout regions (86) which are adapted to be removed from panel structures disposed at the sides of the rack such that associate rib pairs slidably receive the dividers. Each divider has a display box supporting area (200), a display box retaining projection (206), an extra parts supporting area (202), a pair of guide edges (220, 222) which are slidably received in rib pairs of opposite side panels, and a handle (240) for facilitating manual sliding of the dividers.
