This 72 x 24 x 86" four-shelf chrome wire shelving add-on unit is engineered to extend an existing starter shelving system by sharing a pair of uprights, reducing the total hardware needed to grow your storage footprint. Each unit ships with four wire shelves, two upright posts, and eight S-hook connectors.

Warehouses, distribution centers, retail stockrooms, and manufacturing facilities use add-on units to scale shelving runs efficiently. Units support straight-line, back-to-back, and right-angle (L-shape) configurations, allowing layouts to adapt to available floor space. The open wire surface promotes airflow and shelf-level visibility throughout.

Note that starter units paired with add-on units are not compatible with caster mobility kits. Additional shelves and accessories are sold separately. Due to its 125 lb. weight and overall dimensions, this unit requires freight delivery. Sold individually.
