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, it adds 6 openings across a 48'' W x 10'' D x 76.25'' H footprint - giving records rooms, mailrooms, supply closets, and office storage areas a clean, efficient way to grow alongside their needs.

At 10'' deep, this adder is well suited for letter-size files, binders, small supplies, and similar items that do not require deep shelving. The slim profile makes it a practical choice for narrower aisles or rooms where floor space is at a premium, while the full 76.25'' height takes advantage of vertical space to maximize storage density.

Single entry adder units share a common upright with the adjacent starter section, which reduces the total number of posts needed and keeps the overall system footprint compact. This unit is intended to be added to an existing 4-post shelving run rather than used as a freestanding starter. If you are planning a new shelving installation, begin with a compatible starter unit and use adder sections like this one to build out the run to the length your space requires. The 68 lb product weight reflects a sturdy steel construction suited for active storage environments.

Key Features:

• 6 Storage Openings: Provides six shelf bays in a single adder section, giving you meaningful added capacity with each unit you connect to your run.
• 48'' W x 10'' D x 76.25'' H Footprint: Wide enough for standard storage items while the 10'' depth keeps the unit space-efficient in tighter rooms and narrower aisles.
• Single Entry Adder Configuration: Shares an upright with the adjacent starter section to minimize the number of posts and keep the system footprint as compact as possible.
• Full Vertical Height: At 76.25'' tall, the unit makes use of vertical space to increase storage density without expanding the room's floor plan.
• Sturdy Steel Build: At 68 lbs, this unit is built for the demands of active file, records, and supply 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 extend an existing 4-post shelving system with 6 additional openings in a 10''-deep, 48''-wide, 76.25''-tall profile. It is a practical choice for offices, records rooms, and supply areas that need more organized storage capacity without a full system replacement.
