Middle Atlantic 5510-WH NM Series End Cap, White

Overview

The Middle Atlantic 5510-WH is a white end cap built for the NM Series 5500 rack platform, closing off the exposed side of a rack run and giving equipment racks a finished, enclosed look. On its own it looks like a minor accessory, but on a multi-bay rack lineup, unfinished side panels are one of the fastest ways to make an otherwise clean install look unfinished — the 5510-WH exists to solve exactly that. It's a factory-new, direct-sourced component intended to pair with the NM 5500 rack family, not a universal fit for other rack lines, so confirm your rack series before ordering.

Key Features

• White finish: matches light-colored equipment rooms, data closets, and control environments where a black rack end cap would stand out against white walls and ceiling tile — useful in offices, AV control rooms, and healthcare or education spaces where aesthetics get reviewed by facilities staff.
• TAA compliant: the 5510-WH qualifies for procurement under Trade Agreements Act rules, which matters directly for government, federal contractor, and public-sector buildouts where TAA sourcing is a hard requirement in the bid spec — without this, the rack build can't be used on those jobs regardless of price.
• Purpose-built for the NM 5500 platform: designed specifically to close out NM Series 5500 rack runs rather than as a generic panel, so it lines up with the rack's existing mounting geometry instead of requiring field modification or shimming during install.
• Finishes exposed rack ends: covers the open side of a rack section, which keeps cabling, rail edges, and mounted gear out of view and out of reach in walk-through spaces like server rooms, NOCs, and shared IT closets.

Integration & Compatibility

The 5510-WH is built to close out sections of the Middle Atlantic NM Series 5500 rack line. It's an accessory piece, not a standalone enclosure, so it's meant to be specified alongside NM 5500 rack frames rather than purchased in isolation. If you're speccing a full rack build, review the broader Middle Atlantic catalog for compatible NM Series rack frames, and check the network video recorders and switch gear you're planning to house before finalizing rack width and end-cap count. For teams still working out rack layout and power distribution, a PoE planning guide can help right-size the rack before hardware ships. Pair the finished rack with appropriate rack accessories — cable management, blanking panels, and mounting rail — to keep the build consistent end to end. If your project also involves camera or NVR housings in the same equipment room, cross-reference outdoor IP cameras or indoor camera lines being terminated into that rack.

James Everett

The 5510-WH is a small piece of a rack build, but it's the piece that gets noticed when it's missing. This is the white version of Middle Atlantic's NM 5500 end cap, and I spec it whenever a rack run lands in a space where black hardware would clash with the room.

Technical Highlights:

• White finish: built to match light equipment rooms and control spaces, so the rack doesn't visually clash with white walls or ceiling grid in offices and shared facilities.
• TAA compliance: the 5510-WH clears Trade Agreements Act sourcing requirements, which is a pass/fail gate on a lot of government and federal contractor bids — no TAA compliance, no bid eligibility, full stop.
• NM 5500 platform fit: engineered specifically for the NM Series 5500 rack, so it seats correctly without field trimming or bracket improvisation during install.

Deployment Considerations:

• Confirm your rack frame is actually NM Series 5500 before ordering — this end cap is platform-specific and won't fit other Middle Atlantic rack families.
• Order enough end caps for every exposed side of your rack run up front; mismatched or missing panels on a multi-bay lineup are an easy thing to miss during initial BOM.

The 5510-WH is the right call for a federal or public-sector server room build where TAA compliance is mandatory and the room's finish calls for white rack hardware instead of black.
