This double-entry 4-post adder shelving unit is built to extend an existing shelving run, giving you more organized storage capacity without starting from scratch. At 88.25'' tall with 7 openings and a 26'' depth, it delivers substantial vertical storage in a compact footprint - ideal for offices, records rooms, libraries, government facilities, and any workspace where floor space is at a premium.

The double-sided configuration means both faces of the unit are accessible, making it well suited for aisle-facing installations where staff need to reach stored materials from either side. At 157 lbs, this is a substantial, full-height unit built for demanding storage environments.

Adder units are designed to share a common upright with an adjacent starter or adder section, allowing you to build out a continuous shelving system bay by bay. This unit slots into that system as an expansion piece, so it requires a compatible starter unit or existing run to anchor to. The 30'' W x 26'' D footprint and 88.25'' height should be confirmed against your existing shelving configuration before ordering to ensure a proper fit. This product is made in the USA and carries a limited lifetime warranty when installed by a Certified Installer.

Key Features:

• Double-Sided Access: Open on both faces for aisle-facing installations where retrieval from either side improves workflow efficiency.
• 7 Openings: Generous number of shelf bays across the full height of the unit, supporting flexible organization of files, binders, boxes, or supplies.
• Full-Height Design: At 88.25'' tall, this unit maximizes vertical storage and makes use of ceiling clearance to keep floor space free.
• Adder Configuration: Shares uprights with adjacent sections to create a continuous, space-efficient shelving run without redundant framing.
• Made in the USA: Domestically manufactured for quality assurance and reliable lead times from a Pennsylvania-based facility.
• Limited Lifetime Warranty: Backed by a limited lifetime warranty for the original purchaser when installed by a Certified Installer, with qualifying replacement parts supplied for the product life.

This 4-post double entry adder unit is a practical choice for expanding an existing shelving system in high-use storage environments. Verify compatibility with your current shelving run before ordering, and confirm ceiling clearance for the 88.25'' height.
