This 48 x 24 x 74" wire shelving add-on unit expands an existing starter unit by sharing a common pair of upright posts, eliminating the need for a full second frame and reducing the hardware footprint on the floor. It is sold individually and is not a standalone shelving unit.

The four open-wire shelf levels make this unit well suited for warehouses, stockrooms, retail back rooms, and industrial storage areas where visibility and airflow around stored goods are priorities. Straight-line, back-to-back, and right-angle (L-shape) configurations are all supported, allowing layout flexibility to fit varied floor plans and space constraints.

Each unit ships with four shelves, two upright posts, and eight S-hook connectors — all hardware needed for direct attachment to a compatible starter unit. Note that this starter/add-on combination is not compatible with caster kits for mobile configurations. Unit weight is 79 lbs; freight delivery is required.
