This 36 x 24 x 54" wire shelving add-on unit extends an existing starter unit by sharing a common set of upright posts, reducing total hardware and keeping storage runs compact. Each unit includes four wire shelves, two upright posts, and eight S-hook connectors.

The add-on format suits warehouses, stockrooms, fulfillment centers, and retail backrooms where storage capacity needs to grow in line with inventory. Supported layout configurations include straight-line, back-to-back, and right-angle (L-shape) arrangements, allowing operations to adapt shelving runs to available floor space.

The unit weighs 64 lbs and is sold individually. Note that a starter-and-add-on combination cannot be fitted with casters for mobility. Additional shelves and accessories are available separately to adjust shelf spacing. Freight delivery required.
