This 60 x 36 x 63" wire shelving add-on unit expands an existing starter unit by sharing a common set of posts, increasing storage capacity without requiring a second standalone frame. Each unit includes four shelves, two posts, and eight S-hook connectors — all components needed for direct attachment to a compatible starter unit.

Supported configurations include straight-line, back-to-back, and right-angle (L-shape) arrangements, making this unit adaptable to varied floor plans in warehouses, stockrooms, fulfillment centers, and retail back-of-house environments where maximizing linear shelf runs is a priority.

This add-on is compatible with the matching starter unit in the same footprint and height. Note that casters cannot be used on a combined starter and add-on configuration. Additional shelves and accessories are sold separately. Weighing 129 lbs, this unit ships via freight. Sold individually.
