A correctly specified cantilever system provides safe, orderly storage for long, bulky materials like tubing, pipe and building supplies. You can include as many arms as necessary to provide the storage density you need, as long as you allow proper load clearance and do not exceed the upright capacity. Make sure to select an arm length that equals or exceeds the load depth; loads that hang over the end of the arm can damage the system or cause a failure. This model is 36" long with no lip.
