This 48 x 24 x 86" wire shelving add-on unit extends an existing starter unit by sharing a common set of posts, adding four full shelves of storage capacity without duplicating the full post hardware. Each unit includes four shelves, two posts, and eight S-hook connectors — a complete hardware set for the add-on configuration.

The open wire deck construction promotes airflow and sightline visibility across all levels, making these units well suited for warehouse aisles, stockroom organization, retail backrooms, and light manufacturing environments where inventory accessibility matters. Supported layout configurations include straight-line, back-to-back, and right-angle (L-shape) arrangements.

This unit requires a compatible starter unit to function and is not compatible with caster mobility when joined to a starter configuration. Additional shelves and accessories are sold separately. Unit weighs 81 lbs and ships freight. Sold individually.
