The 12' Single-Sided Cantilever Rack Starter Unit is a heavy-duty storage solution built for warehouses, distribution centers, lumberyards, and industrial facilities that need to store long, bulky materials efficiently. At 12' tall with 48" arms and 3 storage levels, it delivers 11,704 lbs of capacity per side in a fully open-front design — no vertical obstructions, no wasted space.

Ships complete with 2 columns, arms, and brace sets — everything needed to assemble your first bay. Arms adjust every 4" the full height of the column. Each base requires 4 standard anchor bolts to secure to the floor (not included). Outdoor-ready with a durable powder-coated finish — corrosion-resistant and built to perform in demanding indoor and outdoor environments. A galvanized finish is available upon request for added protection.

What's Included

• 2 columns (12' / 144" height, 5" x 10" H-profile, blue powder coat)
• Cantilever arms (48" length, 3,960 lb capacity each, orange powder coat)
• Brace sets per column height (blue powder coat)
• All hardware for assembly

Why the 12' Single-Sided Starter

Open-front design for maximum accessibility — No vertical supports interrupt the storage face. Load and unload with a forklift or crane from the aisle without obstruction, ideal for pipes, lumber, steel bar, fabric rolls, and metal profiles of varying lengths.

Fully adjustable arms — Arms lock into the column at 4" intervals the full height of the upright, letting you customize each level to exactly match your load dimensions without any tools.

Tool-free pipe stop end installation — Optional pipe stop ends (sold separately) drop into place with no tools required, preventing cylindrical loads from rolling off the end of the arm.

Outdoor-ready, maintenance-free construction — Impact-resistant powder-coated steel stands up to demanding indoor and outdoor environments. Galvanized finish available on request for maximum corrosion protection.

Grows with your operation — Add 12' Single-Sided Cantilever Rack Add-On Units at any time to extend into a continuous row system. Each add-on shares a column with the adjacent unit, eliminating redundant uprights and maximizing floor space.

Engineered to RMI specifications — Seismic analysis, stamped drawings, and engineering calculations available upon request.
