When your existing shelving system runs out of room, this 4-Post Single Entry Adder Unit lets you extend your storage capacity without starting over. Designed to connect to a compatible 4-post starter bay, it adds 6 openings across a 42'' W x 16'' D x 76.25'' H footprint - giving you a full column of organized, accessible shelf space that integrates cleanly into your current layout.

At 16'' deep and standing over 76'' tall, this adder is well suited for offices, records rooms, libraries, warehouses, and facilities that need to grow their shelving runs incrementally. The single entry configuration keeps the unit compact and efficient, making it a practical choice wherever floor space is at a premium.

Adder units are the building blocks of a scalable shelving system. Rather than purchasing a freestanding unit, an adder shares a common upright with the adjacent bay, reducing the total number of posts needed and keeping your shelving rows tight and stable. This unit ships at 135 lbs, so plan for appropriate receiving and installation resources. Because this is a configured shelving product, lead times may vary - consult your project team for current availability and installation requirements.

Key Features:

• 6 Openings: Provides six shelf bays of accessible storage space, supporting organized retrieval across a full-height run.
• Single Entry Adder Configuration: Designed to attach to an existing 4-post starter bay, sharing uprights to maximize floor efficiency and keep rows uniform.

• Scalable System Design: Add one or more adder units to a starter bay to build out shelving runs as your storage needs grow over time.

This 4-Post Single Entry Adder Shelving Unit is a straightforward way to extend an existing shelving system with 6 additional openings in a space-efficient 42'' W x 16'' D x 76.25'' H profile. Review installation requirements and confirm starter bay compatibility before ordering.
