16' Double-Sided Cantilever Rack Starter Unit

Double-Sided Cantilever Rack Starter Unit — 16' High, 48" Arms, 11,660 lb per Side

Who it's for: Lumberyards, steel and pipe distributors, fabricators and warehouses that need to load from both aisles. This Space Plus USA starter unit has 2 columns 16' tall and 48" arms rated 3,960 lb each on both sides, in an open-front design you can load by forklift or crane from either aisle.

Best for: access from both aisles, forklift or crane loading from either side, indoor or outdoor storage with a powder-coated finish (galvanized on request), and starting a double-sided row you can extend with add-on units.
Not the best fit for: single-side access only, where the 16' single-sided starter unit costs less. For palletized goods, a teardrop pallet rack fits better. Already have this starter? Add bays with the 16' double-sided add-on unit. Need a different height? See the 12' Double-Sided Cantilever Rack Starter Unit.

What makes it different

• Load from both aisles: arms on both sides of every column give two full storage faces, doubling throughput for high-volume operations without taking more floor space.
• Arms adjust every 4": arms lock into the column at 4" intervals the full height of the upright, without tools, to match your load sizes on each side independently.
• Indoor or outdoor: impact-resistant powder-coated steel, with a galvanized finish available on request, engineered to RMI specifications.

Why the 16' Double-Sided Starter Unit

Load from both aisles — Arms run on both sides of each column, so your team can pick and replenish simultaneously from either aisle. Ideal for high-throughput lumberyards, steel service centers, and pipe distributors.

Fully adjustable arms — Arms lock into the column at 4" intervals the full height of the upright, letting you customize each level and each side 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 16' Double-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.

FAQ

How much weight can the double-sided unit hold?

Each 48" arm is rated 3,960 lb (evenly distributed load), and the column capacity is 11,660 lb per side based on the 48" arm length. Keep loads centered and no longer than the arm. Each side is independent — both sides can be loaded simultaneously to their full per-side capacity.

What is the difference between the 48" and 60" column spacing options?

Both options use 48" arms and the same 11,660 lb per side capacity. Column spacing is the distance between columns. Choose wider spacing for longer materials that need more horizontal clearance between uprights. See our cantilever rack buying guide for guidance on matching spacing to your material lengths.

What is the difference between a double-sided and a single-sided unit?

A double-sided unit has arms on both sides of every column, letting you store and access loads from two aisles. A 16' single-sided unit has arms on one side only and costs less. Use double-sided when you need two-aisle access or want to maximize storage per linear foot of floor space.

What comes in the box?

2 columns, cantilever arms on both sides, brace sets and all hardware — everything needed to assemble your first double-sided bay.

Can the arms be adjusted?

Yes. Arms lock into the column every 4" the full height of the upright, with no tools needed. Each side can be configured independently.

Can it be used outdoors?

Yes. The powder-coated finish is corrosion-resistant and built for indoor and outdoor use. A galvanized finish is available on request for more protection in outdoor or high-humidity areas.

Are floor anchors included?

No. Each base needs 4 standard anchor bolts to secure it to the floor before use. Anchors can be bought locally or provided by us at additional cost. Check local building codes for requirements.

Can I stop pipe from rolling off the arms?

Yes. Tool-free pipe stop ends drop onto the arms to keep cylindrical loads from rolling off. They are sold separately.

How do I extend the row?

Add 16' double-sided add-on units at any time. Each add-on shares a column with the unit next to it, so you don't need a second set of uprights.

Are engineering drawings available?

Yes. The rack is engineered to RMI specifications, and stamped drawings, seismic analysis and engineering calculations are available on request.
