Middle Atlantic 5506B-WH NM Base 5500 Series Seam Clip

Overview

The Middle Atlantic 5506B-WH is a seam clip built for the NM Base 5500 series rack enclosure line, finished in white to match light-colored equipment rooms, network closets, and AV integration spaces where a black clip would stand out against a white frame. Evidence on this specific part is limited to color, TAA status, and its designation as an NM Base 5500 seam clip — so this page sticks to what's confirmed rather than guessing at dimensions or torque specs that aren't in the manufacturer data provided. Integrators specifying 5506B-WH (often searched as 5506B WH) alongside an existing 5500 series enclosure should confirm exact panel compatibility with their specific rack configuration before ordering, since seam clip fitment is enclosure-specific across rack families.

Key Features

• White finish: matches NM Base 5500 series enclosures and panels finished in white, avoiding a mismatched black clip on an otherwise white rack seam — relevant for visible installs in offices, classrooms, and retail back-of-house where appearance matters as much as function.
• TAA compliant: sourcing meets Trade Agreements Act requirements, which matters directly for integrators bidding federal, state, or other government-funded projects where TAA status is a hard procurement gate rather than a nice-to-have.
• Purpose-built for the 5500 series: designed specifically for NM Base 5500 series construction rather than sold as a universal clip, so fit and finish should be more consistent than a generic hardware substitute.

Integration & Compatibility

The 5506B-WH is designated for the NM Base 5500 series platform within the Middle Atlantic catalog. If you're speccing a full enclosure build rather than a single hardware item, review the broader rack enclosures category alongside a rack planning guide to confirm the 5500 series is the right platform before ordering seam clips or other frame hardware.

The 5506B-WH is a small part, but on a white 5500 series build it's the kind of detail that separates a clean-looking rack from one with mismatched black hardware showing at every seam.

Technical Highlights:

• White finish: matched specifically to NM Base 5500 series white enclosures rather than a generic paint-match, so it holds up under close inspection on visible installs.
• TAA compliance: sourcing that clears procurement on government and public-sector jobs without a separate compliance conversation.
• 5500 series fitment: built for the NM Base 5500 platform specifically, not a universal clip repurposed across enclosure families.

Deployment Considerations:

• Confirm your enclosure is actually 5500 series before ordering — Middle Atlantic runs multiple NM Base platforms and seam hardware isn't always cross-compatible.
• Available spec data on this part is limited; if you need exact dimensions or torque ratings for a spec sheet submittal, verify against the physical part or your rack drawings before finalizing a bid.

Right part for a white 5500 series enclosure build going into a visible space — a conference room AV closet or a reception-area rack — where mismatched black hardware on a white frame would be the first thing a client notices on walkthrough.
