This complete starter lets you easily implement cantilever storage for long, heavy materials like lumber, pipe and rolls. This model includes two 12' uprights, 48" inclined arms and 72"W bracing. You can use adders to create a row of racking and additional arms for extra storage density (as long as you don't exceed the upright capacity). Other sizes and capacities are available. Just contact us for help with specifying the right system.
