This 48 x 18 x 86" wire shelving add-on unit expands an existing starter unit configuration by sharing a common set of uprights, reducing material cost and floor space compared to installing a second freestanding unit. Each unit ships with four wire shelves, two posts, and eight S-hook connectors.

The open-wire design supports airflow, visibility, and easy access, making it well suited for warehouses, distribution centers, manufacturing floors, retail stockrooms, and cold-storage environments. Supported layout configurations include straight-line runs, back-to-back arrangements, and right-angle (L-shape) builds, giving facilities flexibility in how storage capacity is structured.

Note that a starter unit with an attached add-on is not compatible with caster installations and cannot be made mobile. Additional shelves and accessories are sold separately. Freight delivery required due to overall size and unit weight. Sold as one unit per order.
