ABSTRACT:
A stacking member for stacking one hamper cart on another hamper cart is provided that is easily installed, removed, and stored nested with other like stacking members. The stacking member is strong, yet relatively light weight, and functions, among other things, (1) to distribute the weight of the stacked cart evenly and to a major portion of the length of each sides and ends of the upper frame of the supporting cart, (2) index itself for quick installation in the proper position on the upper frame of the supporting cart, (3) orient and index the supported cart on the stacking member, (4) secure the stacked cart on the stacking member to prevent sliding or movement during transport by pinching or gripping the shifting, fixed axis center caster wheels, and (5) allow imprecise transverse placement of the stacked cart on the stacking member.
