Cantilever Rack Arm with 2″ Bolt-on Lip on End of Arm

A cantilever rack arm with a 2″ bolt-on lip is a horizontal storage arm that attaches to a cantilever rack upright and features a raised steel lip welded or bolted to the outer end of the arm. This lip extends 2″ above the arm surface, creating a stop that prevents materials from sliding off the end of the arm during storage and handling. The bolt-on design allows the lip to be added to existing straight arms without replacing the entire arm, providing flexibility for facilities that need to upgrade their storage configuration without purchasing new components. These arms are used in warehouses, lumber yards, building supply operations, and manufacturing facilities that store long, flat, or irregularly shaped materials on their cantilever rack systems.

The 2″ bolt-on lip provides a practical safeguard against stray pieces of material that might shift or migrate toward the end of the arm during normal operations. It is important to note that these lips are not designed to restrain a full load or prevent load failure. They are intended only to catch an individual piece that may work its way toward the end of the arm. This distinction is critical for proper load planning, as materials must still be stored within the rated capacity and dimensions of the arm, with the lip serving as a secondary measure rather than a primary retention device. For materials such as lumber, pipe, bar stock, and sheet goods that can shift slightly during vibration or repeated handling, the lip provides an added layer of protection against stray pieces falling from the rack.

The bolt-on design offers an advantage over fixed-lip arms by allowing facilities to add lips only where needed rather than replacing entire arm sets. Existing straight arms can be retrofitted with bolt-on lips in specific rack bays or at particular arm levels where material movement is a concern, reducing the cost of upgrading storage systems. This selective installation also allows facilities to remove or reposition lips as storage requirements change, maintaining the flexibility that cantilever rack systems are designed to provide. The steel construction of the lip matches the durability of the arm itself.

Lumber yards, steel service centers, and building material distributors rely on these rack arms with lips to maintain organized storage while reducing the risk of stray pieces falling into aisles or work areas. When selecting arms with bolt-on lips, facilities should verify that arm length, capacity ratings, and upright compatibility meet their load requirements, ensuring the overall rack system performs safely and efficiently for their specific storage application.
