Cantilever racks store long materials like lumber and pipe off the floor for better organization and storage density. This 18' single-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 9,200 to 10,400 pounds based on arm length. Just contact us with any questions about how to specify the right system.
