The heavy-duty steel frame of the Edsal Rivet Lock Boltless Tire Rack allows you to store up to 1,000 pounds of tires per level. Rivet-lock design means no bolts, nuts or screws in the assembly. Double-riveted beams lock onto the uprights and adjust in 1 1/2-inch increments to suit your needs. The durable baked enamel finish on the steel resists scratches and other damage. The double-entry lets you access the rack from two sides for twice the storage space.
