Abstract: A shipping container for holding a plurality of parallel panels, the shipping container including a floor, a generally upright rear wall, and a frame supporting the floor and the rear wall at right angles to each other for vertically supporting the parallel panels. The edges of the panels can be supported by the floor and rear wall, with the panels being supported in parallel planes perpendicular to the planes of the rear wall and floor. The floor can have numerous parallel grooves for receiving the panel edges and numerous upwardly protruding holding members slidably disposed along a direction transverse to the floor grooves and received panel edges. The holding members can have a relaxed position for permitting removal of the panels and the gripping position for inhibiting movement of the panels.
