Middle Atlantic 40N2F20WH NM End Fitting

The Middle Atlantic 40N2F20WH is an end fitting for the 40N series cable raceway, finished in white to match light-colored rack and wall installations. It's a small part with one job: close off the open end of a 40N raceway run cleanly, so cabling stays contained and the installation looks finished instead of like an unterminated channel. For integrators standardizing on Middle Atlantic's 40N raceway across a rack room or equipment closet, the 40N2F20WH is the correct finishing piece when the rest of the run is specified in white.

Overview

This end fitting is purpose-built for the 40N raceway platform, not a universal or generic cap. If you've already committed to 40N channel for horizontal or vertical cable management, the 40N2F20WH is the matching termination component rather than a workaround. Ordering the fitting in the same white finish as the raceway avoids a mismatched, two-tone look at the point where a run ends against a wall, rack frame, or equipment bay — a detail that matters in visible install locations like conference rooms, lobbies, and control rooms where the rack or raceway is not hidden behind a closed door.

Key Features

• White finish: matches 40N raceway and enclosures ordered in white, so a terminated run reads as one finished assembly instead of a raceway body capped with a mismatched part.
• TAA compliant: the 40N2F20WH meets Trade Agreements Act sourcing requirements, which matters if this fitting is going into a GSA schedule buildout, a federal facility, or any project where TAA compliance is a line-item requirement for every component on the BOM — not just the headline equipment.
• Dedicated 40N-series fitting: engineered specifically for the 40N raceway family, so it seats and finishes correctly rather than requiring field trimming or an adapter to fit a channel it wasn't designed for.
• Low-profile finishing component: closes the exposed end of a raceway run, which keeps cable bundles from spilling out at the termination point and keeps the installation code-neat and visually clean for client-facing spaces.

Integration & Compatibility

The 40N2F20WH is designed to pair with Middle Atlantic's 40N raceway line — confirm your existing or planned raceway run is specified as 40N series before ordering, since end fittings in this family are sized and shaped to a specific channel profile and are not interchangeable across Middle Atlantic's broader raceway lineup. This part is a finishing accessory, not a structural or load-bearing rack component, so it should be specified alongside the raceway itself rather than as a standalone fix for an unrelated channel. When you're planning a full cable management path for a rack room, it's worth reviewing rack accessories and cable management options as a set, and checking a PoE and cabling planning guide if the raceway is carrying camera or network drops rather than just power. Pair it with the rest of the Middle Atlantic catalog for enclosures, rack rail, and raceway sections finished to match, and if the run is feeding IP cameras or access control panels, cross-reference it against nearby network video recorders or head-end equipment placement so the raceway path lines up with where those devices actually land in the rack.

Frequently Asked Questions

Q: Is the 40N2F20WH TAA compliant?

A: Yes, the 40N2F20WH is TAA compliant, which supports its use in GSA and federal procurement projects.

Q: What color is the 40N2F20WH available in?

A: This part is finished in white, intended to match 40N raceway and enclosures ordered in the white finish.

Q: Does the 40N2F20WH fit any Middle Atlantic raceway?

A: No — it's built specifically for the 40N raceway series and is not confirmed interchangeable with other Middle Atlantic raceway families.

Q: Is the 40N2F20WH a structural rack component?

A: No, it's a finishing end fitting for capping a raceway run, not a load-bearing or structural rack part.

Ted Perry

The 40N2F20WH is one of those parts that never shows up on a project's exciting-equipment list but gets flagged immediately on a punch-list walk if it's missing. It's the white end fitting for Middle Atlantic's 40N raceway, and I spec it whenever a 40N run is going in a white rack room or client-visible space and terminates somewhere other than a wall penetration.

Technical Highlights:

• White finish: matches 40N raceway sections and enclosures ordered in white, so the terminated end doesn't stick out as an off-color patch job.
• TAA compliance: the 40N2F20WH is confirmed TAA compliant, which I check on every line item for federal and GSA schedule jobs — it's an easy part to overlook until procurement kicks it back.
• 40N-series specific fit: this fitting is built for the 40N raceway profile specifically, not a universal cap, so it seats correctly without field modification.

Deployment Considerations:

• Confirm your raceway is actually specified as 40N series before ordering — Middle Atlantic runs multiple raceway families and end fittings aren't cross-compatible between them.
• Order finish to match: mixing a white end fitting on a black raceway run (or vice versa) is a common punch-list callback on finished, client-facing installs.

I'd spec the 40N2F20WH on any white-finish 40N raceway run terminating in a visible space — a conference room credenza, a lobby equipment closet, or a control room where the raceway isn't hidden behind a locked door.
