This 4-post double entry adder unit is designed to extend an existing 4-post shelving system, giving facilities managers, records rooms, and warehouse operations a straightforward way to grow storage capacity without starting from scratch. At 30'' W x 32'' D x 88.25'' H with 7 openings, it provides generous vertical reach and open-bay access from both sides, making it well suited for high-density storage environments where efficient use of floor space matters.

The double entry configuration allows access from either aisle face, which supports organized retrieval workflows in back-to-back or mobile shelving arrangements. As an adder unit, it connects to a compatible starter section to form a continuous run, keeping your storage layout clean and structurally sound.

This unit fits into planned shelving runs where additional bays are needed alongside an existing starter section. The 7-opening layout gives you flexibility to configure shelf levels to match the height of your stored items, whether that is binders, boxes, bins, or other materials. The tall 88.25'' height makes full use of vertical space, and the 32'' depth accommodates standard storage containers and file boxes with room to work. At 188 lbs, this is a substantial, heavy-duty unit intended for professional installation as part of a larger shelving system build-out.
