This 5-tier double-sided rolling bin rack packs 68 PP bins, 48 medium blue bins plus 20 large gray bins, into one mobile storage unit for garages, workshops, or busy stockrooms. Each bin locks onto the frame with a peg-back mount, and every bin carries a label slot so you can tag and find parts fast from either side of the rack. Flip-top lids let you add extra storage space on top when you need it, keeping frequently used tools within easy reach. Each tier supports up to 88 lbs, and the whole unit rolls on four rubber swivel casters, two of which lock, letting you push up to 360 lbs of load through tight aisles using the side handle and then park it securely. Built from heavy-duty Q235 steel with a powder-coat finish, the frame resists corrosion over years of use, while the 0.07-inch PP bins stand up to repeated impacts and chemical exposure on a busy shop floor.
