Abstract: This invention is an integrally molded display floor for a gravity feed display tray where the floor has no integrally molded side walls extending upward but has a plurality of longitudinal ribs which can receive upward extending partitions which are releasably attachable to the floor and extend longitudinally, thus dividing the display tray into laterally spaced compartments. Each display tray has opposite marginal side walls extending downward and transversely extending support beams intersecting the longitudinal ribs. The downward extending side walls extend below the bottom surfaces of the longitudinal ribs thus establishing a basement where the bottom surfaces of the ribs constitute the ceiling of the basement. This basement is a space suitable for receiving downward extending tabs of the partition to engage and stabilize such partition with the display track.
