This 4-post single entry adder shelving unit is built to extend an existing shelving run, giving facilities managers, warehouse teams, and office storage planners a straightforward way to add capacity without starting from scratch. At 30'' W x 18'' D x 76.25'' H with 5 openings, it fits neatly alongside a compatible starter unit to create a continuous, organized storage bay that makes better use of available floor space.

The adder configuration shares a common upright with the adjacent unit, which keeps the overall footprint compact and the installation clean. This makes it a practical choice for file rooms, supply areas, stockrooms, and any environment where maximizing linear storage along a wall or aisle is a priority.
