Cantilever racks are steel shelving units with long arms that extend from metal frames used to store long, bulky or awkward materials. They are used to store items such as furniture, lumber, PVC, metal pipes, steel bar stock, plywood, steel sheets, sheetrock and even cars.
Cantilever rack arms extend out from the uprights to create the levels that are used for storage, similar to pallet rack beams. The arms are typically adjustable on the upright to create shelf levels of whatever height are needed. Arms can be straight or inclined to hold goods that may roll off. Some arms even come with a "lip" that attaches to the end of the arm to prevent loads from slipping off the front of the rack.
Cantilever rack braces go between uprights to stabilize the rack laterally. Braces are not intended to hold loads and should only be used to connect and brace the uprights in a row. The braces will be the same length as the spacing between uprights.
