Cantilever racks store long materials like lumber and pipe off the floor for better organization and storage density. This 18' double-sided upright allows you to create the rack system that will work best for your operation by combining it with the arms and braces that fit your product and your floor space. Capacity ranges from 18,400 to 20,800 pounds based on arm length. Just contact us with your questions about specifying a cantilever rack or system.
