This 4-Post Double Entry Adder unit is built to extend an existing 4-post shelving system, giving facilities a cost-effective way to grow storage capacity without starting from scratch. With 7 openings and double-entry access, it supports organized, high-density storage in archives, supply rooms, libraries, and similar environments where space efficiency matters. At 42'' W x 32'' D x 88.25'' H, it delivers substantial vertical storage in a footprint sized for row-based shelving layouts.

Weighing 245 lbs, this is a substantial, commercial-grade adder unit intended for professional installation as part of a configured shelving system. Its double-entry design means items can be accessed from either side of the row, improving workflow in high-traffic storage areas and reducing the need to navigate around shelving to retrieve materials.

Adder units like this one are added to a starter or end unit to create longer shelving runs. The 7-opening configuration provides multiple shelf levels across the full height of the unit, making it well suited for organizing binders, boxes, files, or other uniform storage items. Because this is a configured, quote-based product, buyers should confirm compatibility with their existing 4-post shelving system before ordering. Lead times for configured shelving systems are typically several weeks and may vary based on order specifics.

Key Features:

• Double Entry Access: Open from both sides of the shelving row, improving retrieval speed and workflow in shared or high-traffic storage areas.
• 7 Openings: Multiple shelf levels across the full 88.25'' height maximize vertical storage capacity for files, binders, boxes, and similar items.
• Adder Configuration: Designed to connect to an existing 4-post shelving system, allowing storage capacity to grow incrementally without replacing existing units.
• Substantial Build: At 245 lbs, this unit is built for commercial and institutional environments where durability and long-term performance are required.
• Generous Footprint: The 42'' W x 32'' D profile accommodates deep storage items and fits standard row-based shelving layouts.

This 4-Post Double Entry Adder unit is a practical choice for organizations expanding an existing shelving system. Verify compatibility with your current 4-post starter or end unit before ordering, and confirm installation requirements with your project team.
