Middle Atlantic 2310B-WH Blank End Panel

The Middle Atlantic 2310B-WH is a blank end filler panel finished in white, built to close off open rack frame ends on NM-series enclosures. If you're finishing out a rack elevation and don't want an exposed frame edge staring back at you in a server room, network closet, or AV rack — this is the part that solves it. The 2310B-WH (often searched as 2310B WH) is a straightforward hardware component, but getting the color and fit right matters more than most integrators expect once a rack is visible to end users or auditors.

Overview

Rack end panels like the 2310B-WH exist to give an NVR or switch rack a finished appearance and to close gaps at the frame ends where cabling, dust, or stray hands could otherwise get in. White is a less common finish than black in most data closets, which makes the 2310B-WH a fit for environments where the rack itself is white-powder-coated — clean rooms, healthcare IT closets, retail back-of-house, or any install where the rack matches white wall infrastructure rather than standard black IT gear.

Key Features

• White finish (WHI): matches white-frame rack systems instead of forcing a black panel into a white elevation — a small detail that matters when the rack is in a visible or client-facing space rather than a hidden closet.
• Blank end panel design: closes the open end of an NM 2300-series rack frame, keeping the frame's structural end from being left exposed after installation.
• TAA-compliant: relevant if you're specifying for a government, education, or federal-adjacent contract where Trade Agreements Act sourcing rules apply to the bill of materials.
• Model-specific fit: designed for the 2300 series frame family (2310B-WH), so pair it against the actual frame model you're finishing rather than assuming universal fit across Middle Atlantic's broader Middle Atlantic catalog.

Integration & Compatibility

The 2310B-WH is a frame accessory, not a standalone enclosure — plan it alongside the specific NM 2300-series rack frame it's built to close out. When you're speccing a full rack elevation, it's worth reviewing a rack and enclosure planning guide before finalizing part numbers, since end panels, side panels, and frame components are matched by series rather than interchangeable across product lines. If the rest of the elevation includes network switches or PoE gear, confirm cable management clearance at the frame end before ordering the blank panel, since some builds route cable behind the end panel rather than through open bays.

Karl Wilson

The 2310B-WH shows up on my BOMs almost exclusively for white-frame installs — healthcare IT closets and clean-room server rooms where a black end panel would stick out against a white NM 2300 frame. It's a small part, but the finish call matters more than people think once the rack is behind glass or in a visible corridor.

Technical Highlights:

• White (WHI) finish: matches white-powder-coat NM 2300 frames instead of defaulting to black, which is the finish most installers stock and grab without checking.
• TAA compliance: lets this part ride along on federal, education, or municipal BOMs where sourcing rules gate every line item, including rack hardware.
• 2300-series specific fit: the 2310B-WH is built for that frame family — it's not a universal blank, so cross-check the frame model before it goes on the order.

Deployment Considerations:

• Order the end panel finish to match the frame finish before the rack ships — swapping a black panel for white after the fact means a second freight charge on a low-cost part.
• This is a cosmetic/structural closure piece, not a cable-management or airflow component — don't spec it expecting ventilation or cable pass-through function.

Reach for the 2310B-WH specifically when you're closing out a white NM 2300-series frame in a visible install — a clinic IT closet, a lab, or any space where the rack itself is part of the finished environment, not tucked in a back room.
