The Vevor 5-tier double-sided rolling bin storage rack is designed to organize tools, parts, and supplies in garages, warehouses, offices, restaurants, and classrooms. It includes 68 organizer bins in two sizes, with label slots for quick sorting and identification. A heavy-duty powder-coated Q235 steel frame and impact-resistant PP bins provide durable everyday storage. Four swivel casters and a side handle make it easy to move, while two locking casters help keep the rack securely in place. The flip-top design adds convenient extra storage space on top.
