This 4-post double entry adder unit is designed to extend an existing 4-post shelving system, giving storage planners a straightforward way to grow capacity without starting from scratch. At 30'' W x 32'' D x 76.25'' H with 6 openings, it fits naturally alongside a starter unit to create a continuous run of accessible, open shelving. The double entry configuration allows access from both sides of the bay, making it well suited for active storage environments where staff retrieve items frequently from either aisle.

Weighing 163 lbs, this is a substantial, commercial-grade unit built to anchor a high-density shelving layout. Its 6 openings provide defined storage zones that keep files, binders, boxes, or supplies organized and easy to locate across the full height of the unit.

Adder units like this one are the building blocks of scalable 4-post shelving runs used in offices, records rooms, libraries, government facilities, and institutional storage areas. Because it connects to a compatible starter section, the adder shares structural support and keeps the overall footprint efficient. The 32'' depth accommodates standard letter- and legal-size filing as well as a wide range of boxed materials, while the 76.25'' height makes full use of vertical space. This unit is a practical choice when an existing shelving run needs more linear footage without a full system replacement.
