This complete cantilever starter lets you easily add off-the-ground storage for long, heavy materials like pipe, extrusions and building materials. This model includes two 12' double-sided uprights, 36" straight arms and 48"W bracing. You can use adders to create a row of racking and additional arms for extra storage density (as long as the upright capacity is observed). We can offer other sizes and capacities. Just contact us for help with specifying the right cantilever system.
