Bin shelving and racks accept multiple rows of bins for separating and organizing tools, parts, and other items so they can be accessed quickly. They are used for storing and displaying items in garages, supply rooms, and warehouses. Stationary bin shelving and pick racks stand on a floor or attach to a wall or similar surface. Mobile bin shelving and pick racks have wheels and can roll when they need to be moved for cleaning or repositioning. Bin rail racks have rails attached to a frame, and plastic bins can be hung from the rails for storing items on the racks.
