This complete cantilever starter lets you easily add off-the-ground, easy-to-access storage for long materials like pipe, extrusions and building materials. This model includes two 12' double-sided uprights for added storage density, 48" straight arms and 71"W bracing. You can use adders to create a row of racking and add arms for extra storage density (as long as the upright capacity is observed). Other sizes and capacities are available. Just contact us for help with specification.
