Carton flow beds are designed to fit into pallet rack. The mini roller design increases product contact; reducing imprinting and providing better flow. The axles are retained in track eliminating pop outs. The sides rails are constructed of durable 13 gauge channel for 50lb PLF capacity. Easy drop-in design. Carton flow beds are ideal for applications where re-slotting occurs frequently and carton width dimensions vary widely or are constantly changing.
