This 72 x 36 x 63" wire shelving add-on unit expands an existing compatible starter unit by sharing a common set of upright posts, reducing hardware requirements and minimizing floor footprint. Included components — four shelves, two upright posts, and eight S-hook connectors — support assembly without additional hardware purchases.

Straight-line, back-to-back, and right-angle (L-shape) configurations are all supported when paired with a compatible starter unit, making this add-on well suited for warehouse storage, stockroom organization, distribution centers, and industrial facilities where maximizing linear shelf runs is a priority. Shelf spacing can be adjusted to accommodate varying product dimensions and load requirements.

Each unit weighs 137 lbs and is sold individually. Note that starter and add-on unit combinations are not compatible with caster mobility kits. Additional shelves and accessories are available separately. Freight delivery is required due to size and weight.
