Middle Atlantic RC3CTCBK 20A/Comm Cutout Flange and Cover

Overview

The RC3CTCBK from Middle Atlantic is a black flange-and-cover connector kit built for the 20A/communications cutout position on compatible Middle Atlantic rack and enclosure systems. Manufacturer data for this specific SKU is limited to configuration and compliance details, so this page covers what's verified rather than guessing at dimensions or fit beyond what's confirmed.

Key Features

• Black flange finish: matches black rack rail and panel hardware in a standard rack enclosures build-out, so you're not mixing finishes on a visible cutout.
• 20A/COMM cutout configuration: the flange (FL) and cover (CV) pair is sized for a combined 20A power and communications pass-through opening, keeping power and data cabling routed through one defined cutout instead of two separate penetrations.
• TAA compliant: relevant for government, education, and other institutional buyers whose procurement rules require Trade Agreements Act compliant sourcing.

Integration & Compatibility

The RC3CTCBK is designed to mate with Middle Atlantic's cutout-based rack and enclosure hardware. Confirm cutout position and rack model compatibility against your specific enclosure drawing before ordering — this page does not have manufacturer fitment data for individual rack SKUs. For broader system planning, a PoE network switch and cable routing plan alongside your rack and cable management guide will help confirm how power and comm pass-throughs should be laid out before cutouts are finalized. Pair this with Middle Atlantic's other rack accessory hardware for a consistent black-finish build.

The RC3CTCBK is a small part that solves a real jobsite problem: getting a 20A circuit and a comm/data run through the same rack cutout without an ugly aftermarket patch. It's flange-and-cover, black finish, TAA compliant — that's the confirmed spec set on this one.

Technical Highlights:

• Black flange (FL) + cover (CV): finish-matched hardware for a clean cutout on black rack rail, avoiding a mismatched silver plate on an otherwise blacked-out elevation.
• 20A/COMM cutout: combines power and communications routing at one defined opening, which simplifies panel layout versus separate single-purpose cutouts.
• TAA compliant: a hard requirement on a lot of government and education rack builds — RC3CTCBK clears that bar.

Deployment Considerations:

• Verify the cutout position and rack model against your enclosure's spec sheet before ordering — this listing doesn't carry manufacturer dimensional data for a fit guarantee.
• If your build needs a different finish or a power-only or comm-only cutout, check Middle Atlantic's broader flange and cover lineup rather than assuming this SKU covers every configuration.

Right fit for an integrator finishing out a black rack elevation who needs one clean 20A/comm pass-through instead of stacking separate cutout plates.
