When your existing shelving system runs out of room, this 4-Post Single Entry Adder Shelving Unit lets you extend your storage capacity without starting over. Designed to connect to a compatible 4-post starter unit, this adder section adds 6 openings across a 48'' W x 16'' D x 76.25'' H footprint, giving you a clean, organized row of shelving that scales with your needs. Whether you are managing files, binders, supplies, or equipment in an office, archive room, or facility workspace, this unit slots into your existing layout and keeps everything accessible from a single entry side.

At 85 lbs, this is a substantial, well-built shelving section intended for permanent or semi-permanent installation. The single entry configuration means shelving is accessed from one side, making it well suited for against-the-wall runs or back-to-back aisle arrangements where space efficiency matters.

This adder unit is the practical choice when you need to grow a shelving run incrementally. Rather than purchasing a full standalone unit, an adder shares a common upright with the adjacent section, reducing the overall footprint and cost of expanding your storage row. The 16'' depth keeps the profile compact while still accommodating standard binders, boxes, and storage containers. With 6 openings across the 76.25'' height, you have meaningful vertical storage capacity that works in standard ceiling-height rooms. Installation by a certified installer is required to qualify for the full limited lifetime warranty coverage.

Key Features:

• Single Entry Adder Configuration: Designed to extend an existing 4-post shelving run by sharing an upright with the adjacent starter unit, saving floor space and reducing material cost compared to a standalone unit.
• 6 Openings: Provides six shelf bays across the full height of the unit, giving you organized, accessible storage for files, binders, boxes, or supplies.
• Compact 16'' Depth: The shallow profile fits comfortably along walls or in narrow aisles while still accommodating standard storage containers and binders.
• Full-Height 76.25'' Frame: Maximizes vertical storage in standard rooms, keeping your footprint small while increasing overall capacity.
• Substantial 85 lb Build: The unit weight reflects a solid, durable construction intended for long-term use in demanding storage environments.
• 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 Single Entry Adder Shelving Unit is a straightforward way to grow a shelving system row by row. At 48'' W x 16'' D x 76.25'' H with 6 openings, it fits neatly into office, archive, and facility storage plans where organized, expandable shelving is a priority.
