This 48 x 18 x 54" chrome wire shelving add-on unit extends an existing compatible starter unit by sharing a common post set, eliminating redundant hardware and reducing cost per shelf tier. Each unit ships complete with two posts, four shelves, and eight S-hook connectors.

Suited for warehouse storage runs, stockroom bay expansions, retail backrooms, and light industrial environments where maximizing linear shelf space is a priority. Add-on units support straight-line, back-to-back, and right-angle (L-shape) arrangements to work within existing floor plans. Note that a starter-and-add-on combination is not compatible with caster mobility kits.

Chrome wire construction weighs approximately 60 lbs per unit. Additional shelves and accessories are available separately for further customization. Sold individually; the companion starter unit must be ordered separately when building a new shelving run from scratch. Freight delivery required.
