Louvered panels and racks have openings (or louvers) that accept a variety of plastic hanging bins and other compatible accessories for storing and organizing tools, fasteners, and various loose items. The bins and accessories can be reconfigured or replaced as storage needs change, and the bins can be removed and taken to workbenches or other locations as needed. Louvered panels and racks are used in work areas where fasteners and other small parts are used, such as service or production facilities. Stationary louvered panels and racks attach to a wall or similar surface or stand on a floor or workbench. Mobile louvered racks have wheels and can roll when they need to be moved for cleaning or repositioning. Louvered panel shelves, hooks, and hangers attach to louvered panels and racks to expand the range of items that can be stored or displayed on them.
