The bins and compartments on these storage units separate and organize tools, parts, merchandise, and other items so they can be accessed quickly. The storage units are used for storing and displaying items in garages, offices, supply rooms, retail stores, and warehouses. Bin shelving, racks, and rails hold bins and are open to keep their contents accessible. Compartmented shelving units have cubbies or other compartments for storing and displaying items. Sectional stacking bin units have multiple bin compartments stacked on top of one another. Revolving storage bins have tiers or rows of compartmented storage and rotate to provide access to all sides of the storage bins.
