Engineered Heavy-Duty Cantilever Solutions
Standardized configurations and specialized arm designs built to safely organize oversized inventory without horizontal column interference.
System Specifications
High-grade structural steel columns, multi-tier load arms, and custom bolt-down base options engineered to exact weight tolerances.
Lumber Storage Racks
Outdoor covered and indoor cantilever setups optimized for sheet goods, timber, plywood packs, and building materials.
Furniture & Bulky Goods
Obstruction-free continuous surface decking ideal for furniture distribution centers, roll goods, and crated merchandise.
Custom Engineered Profiles
Single-sided or double-sided layouts fitted with material retainers, pipe chocks, and custom guide-rail integrations.
Storage for Lumber, Tube, Pipe, and Structural Stock
The Unarco Racking Cantilever Rack system is precision-engineered to manage loads of varying length, profile, and proportion without vertical or horizontal entry limitations. Unlike conventional selective pallet racking, cantilever systems do not use front upright columns, providing complete, unobstructed forklift access to every level.
This allows entire run lengths to function as active storage capacity. Materials of differing dimensions can be placed along the same continuous shelf beam or supported directly on sturdy cantilever arms, drastically cutting handling times and reducing damage during loading and retrieval.
Manufactured from premium heavy-gauge structural steel, Unarco Racking cantilever columns are pre-punched on both sides. This enables warehouses to seamlessly convert a single-sided wall configuration into a high-density double-sided aisle system as storage requirements evolve.

Patented Hardware & Rigorous Structural Integrity
Every Unarco Racking cantilever system is built to withstand rigorous industrial impacts and heavy cyclic stresses.
Solid One-Piece Column Construction
Factory-welded one-piece column and base units offer rigid, out-of-the-box structural alignment that minimizes field assembly labor and ensures total vertical stability.
Proprietary Key-Wedge Pin Connectors
Our heavy-duty shear pins replace up to four traditional bolts per arm. One Unarco Racking cantilever pin delivers the shear resistance of five standard 5/8-inch bolts without loosening over time.
Positive Locking Arm Design
Cantilever arms lock securely into down positions and will not dislodge from forklift impact or load placement, yet remain easily reconfigurable in 3-inch vertical increments.
Tall Free-Standing Heights
Engineered uprights reach up to 48 feet without requiring top-ties that typically restrict forklift mast clearance and complicate upper-level load maneuvering.
Slotted Narrow Aisle Guide Bases
Specially engineered low-profile slotted base columns enable narrow-aisle guide rails to sit within the rack footprint, maximizing floor capacity per square foot.
Tailored Accessory Integration
Optional shelf trays, axle holders, pipe stops, and steel decking can be quickly integrated to manage bar stock, cylindrical profiles, and non-palletized cargo.
