Middle Atlantic NM Entrance END Fitting P - PN10F21FW

Middle Atlantic PN10F21FW Cable Entrance End Fitting

Overview

The Middle Atlantic PN10F21FW is a fog white cable entrance end fitting designed to feed cables cleanly into PN10 series raceway. If you're terminating a run of cable management raceway and need a professional, finished entry point rather than an open-ended trough, this is the piece that closes the loop. The PN10F21FW includes concentric 1/2" and 3/4" trade-size knockouts, giving you a clean, field-selectable conduit entry without having to source separate fittings.

Part of the broader Middle Atlantic cable management line, the PN10F21FW is built to match PN10 series raceway dimensions exactly — no shimming, no adapter plates. For AV racks, security equipment rooms, and structured cabling runs where appearance and code compliance both matter, this fitting handles the transition from open cabling to enclosed raceway without improvising.

Key Features

• Concentric 1/2" and 3/4" trade-size knockouts: Both knockout sizes are nested concentrically in a single slug — punch the outer ring for 3/4" conduit, or leave it intact and knock the inner for 1/2". One fitting covers the two most common conduit trade sizes, which means fewer SKUs to stock and no field surprises when the conduit size changes at the last minute.
• PN10 series compatibility: Dimensioned and engineered specifically for the PN10 raceway family. An end fitting that doesn't belong to the same product series introduces alignment gaps and finish mismatches — this one snaps flush and maintains the raceway profile from end to end.
• Fog white finish: The fog white color matches standard PN10 series raceway and is appropriate for suspended ceiling and above-ceiling installations where the raceway is visible from below. Using a mismatched color on an end cap is a detail that customers and inspectors notice; this eliminates that issue.
• Clean cable ingress, no sharp edges: As a purpose-built entrance fitting, the PN10F21FW provides a smooth, protected entry path that prevents cable jacket abrasion at the raceway entry point — a concern on long runs where cables move or vibrate.
• Structured cabling and low-voltage applications: Sized and rated for the low-voltage structured cabling environment typical of security, AV, and IT distribution runs — not an industrial conduit body, but the right solution for the environment it's designed for.

Integration & Compatibility

The PN10F21FW is designed exclusively for the Middle Atlantic PN10 raceway and duct series. Before ordering, confirm your existing raceway is PN10 series — Middle Atlantic produces multiple raceway families, and end fittings are not interchangeable across series. The concentric knockouts accept standard 1/2" and 3/4" EMT or flex conduit trade sizes, which align with the conduit sizes most commonly used for low-voltage security and AV cable runs. If your conduit entry point requires a different trade size or a different raceway series, verify the matching fitting part number before purchasing.

For complete rack and enclosure cable management planning — including horizontal managers, vertical cable guides, and blanking panels — the PN10 series offers a full family of components that install without mix-and-match compromises.

Frequently Asked Questions

Q: What raceway series is the PN10F21FW compatible with?

A: The PN10F21FW is designed specifically for the Middle Atlantic PN10 series raceway. It is not a universal fitting and should not be assumed compatible with other Middle Atlantic raceway families or third-party products.

Q: What conduit sizes do the knockouts on the PN10F21FW support?

A: The PN10F21FW includes concentric 1/2" and 3/4" trade-size knockouts. Both sizes are nested in a single slug, giving you a field choice between the two most common low-voltage conduit trade sizes.

Q: Is the PN10F21FW suitable for outdoor installations?

A: No outdoor or environmental rating is indicated in the product evidence. The PN10F21FW is intended for interior structured cabling and cable management applications typical of equipment rooms, AV installations, and security infrastructure.

Q: Does the fog white finish match standard PN10 series raceway?

A: Yes. The fog white finish is the standard color for the PN10 series, so the PN10F21FW end fitting matches the raceway color directly without a separate paint or finish step.

Q: Can the PN10F21FW be used as both an entry and exit fitting on a raceway run?

A: The product is described as an entrance end fitting for feeding cables into raceway. Verify with Middle Atlantic's PN10 series documentation whether a separate exit-end fitting is required for your specific run configuration.

The detail that separates a clean installation from a cobbled one is often something as small as a proper end fitting. The PN10F21FW addresses that exactly — it's the purpose-built termination piece for PN10 series raceway, and the concentric 1/2" and 3/4" trade-size knockouts mean you're not cutting custom holes or improvising a conduit entry at closeout.

Technical Highlights:

• Concentric dual knockout (1/2" / 3/4"): A single slug handles both common low-voltage conduit trade sizes — knock out the outer ring for 3/4" or just the inner for 1/2". That's one fitting covering the two sizes you'll encounter on most security and AV runs.
• PN10 series-specific fit: Engineered to the PN10 raceway profile — not a generic end cap. Proper dimensional match means no gaps at the raceway terminus and a finished appearance that holds up on visible overhead runs.
• Fog white color match: Matches PN10 series raceway directly. On installations where the raceway is visible — suspended ceilings, above-counter AV runs — a mismatched end fitting is a punch-list item. This eliminates it.

Deployment Considerations:

• Confirm your raceway is specifically PN10 series before ordering — Middle Atlantic's other raceway families use different fittings, and there's no universal end cap across the line.
• No environmental or IP rating is specified for this fitting; plan to use it in interior conditioned or semi-conditioned spaces only. Don't rely on it for wet or outdoor conduit entry without verifying additional protection.

The PN10F21FW is the right call for security integrators finishing a PN10 raceway run in a commercial equipment room or structured cabling pathway — particularly where conduit entry size is still being finalized at rough-in and you need the flexibility to go either 1/2" or 3/4" at closeout.
