This 4-post single entry adder shelving unit is designed to extend an existing 4-post shelving run, giving facilities managers, warehouse teams, and office storage planners a straightforward way to add capacity without starting from scratch. At 48'' W x 10'' D x 88.25'' H with 7 openings, it fits neatly into high-density storage layouts where vertical space is at a premium and organized access to files, binders, or supplies is a daily need.

Because it is configured as a single entry adder, this unit shares a common upright with an adjacent starter or adder section, keeping the overall footprint compact while maximizing the number of usable shelf openings per linear foot of floor space.

Adder units like this one are the building blocks of scalable 4-post shelving systems. They are commonly used in records rooms, libraries, government facilities, and back-office storage areas where rows of shelving must grow incrementally as storage needs increase. The single entry configuration means access is from one side, making it well suited for against-the-wall or back-to-back row arrangements. At 88.25'' tall, the unit takes full advantage of standard ceiling clearances, and the 10'' depth keeps the profile slim for aisles where space is limited.

Key Features:

• 7 Shelf Openings: Provides multiple levels of organized storage in a single vertical run, reducing clutter and keeping materials easy to locate.
• Single Entry Adder Configuration: Shares an upright with an adjacent section to minimize floor space used while expanding total system capacity.
• 48'' W x 10'' D x 88.25'' H Footprint: A slim 10'' depth keeps aisle clearance intact, and the full 88.25'' height makes efficient use of vertical storage space.
• Scalable System Design: Adder units connect to compatible starter sections, allowing storage rows to grow as needs change without replacing existing components.
• 76 lb Unit Weight: Reflects a sturdy, commercial-grade build suited for demanding records and supply storage environments.

This 4-post single entry adder shelving unit is a practical choice for any facility looking to extend an existing shelving system with a slim-profile, high-capacity section. With 7 openings across a full 88.25'' height and a 10'' depth that keeps aisles clear, it supports organized, efficient storage in records rooms, libraries, and office storage areas.
