16' Single-Sided Cantilever Rack Add-On Unit

Single-Sided Cantilever Rack Add-On Unit — 16' High, 48" Arms, 11,660 lb per Side

Who it's for: Lumberyards, steel and pipe distributors, fabricators and warehouses that already have a 16' Space Plus USA single-sided cantilever starter unit and want to extend the row. This add-on ships with 1 column, 48" arms rated 3,960 lb each and brace sets, and shares a column with the unit next to it.

Best for: lengthening an existing 16' single-sided cantilever row, long loads such as pipe, lumber, steel bar, fabric rolls and metal profiles, and adding storage with less steel than a second starter unit.
Not the best fit for: a first or stand-alone unit. An add-on must connect to an existing starter, so start with the 16' starter unit. For palletized goods, a teardrop pallet rack fits better. Building a double-sided row? See the 16' double-sided add-on unit. Need a different height? See the 12' add-on unit.

What makes it different

• Open front: no vertical supports block the storage face, so long loads go on and come off from the aisle by forklift or crane.
• 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.
• Indoor or outdoor: impact-resistant powder-coated steel, with a galvanized finish available on request, engineered to RMI specifications.

Key specs at a glance: Column height 16' (192") | Arm length 48" | Arm capacity 3,960 lb each | Column capacity 11,660 lb per side | Arm adjustment every 4"

Why the 16' Single-Sided Add-On

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.

FAQ

How much weight can it 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.

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

Both options use 48" arms and the same 11,660 lb per side rating. Column spacing is the distance between columns. The CRS-AO192X48X48-S (48" spacing) weighs 434 lb and the CRS-AO192X48X60-S (60" spacing) weighs 447 lb. Our cantilever rack buying guide explains how to choose spacing for your material length.
