Middle Atlantic RC3CTCAL Aluminum Flange Cable Connector Opening

The Middle Atlantic RC3CTCAL is a cable connector opening (CO) accessory finished with an aluminum flange and black cover, built for routing 20A power or communications cabling through rack and enclosure surfaces without leaving raw cut edges or an open gap in the panel. It's a small part with an outsized job: keeping a rack face clean, keeping cable runs organized, and giving low-voltage and power conductors a defined, finished pass-through point instead of a hand-cut hole.

Overview

Rack integrators dealing with mixed power and communications cabling need a defined entry and exit point that doesn't compromise the finished look of the equipment rack or the structural integrity of the panel it's mounted to. The RC3CTCAL addresses that directly — it's labeled for 20A/COMM use, meaning it's sized and rated as a routing point for a 20-amp circuit run or communications/low-voltage cable bundle sharing the same opening. The aluminum flange gives the opening a rigid, finished edge, and the black cover closes it off when the opening isn't in active use or needs a clean finished appearance around the cable exit.

Key Features

• Aluminum flange construction: A rigid aluminum edge around the cable opening means no exposed sheet-metal edges that can nick cable jacketing during pull-through — a real consideration when you're routing 20A power conductors through the same rack face as low-voltage comm lines.
• Black cover included: The cover lets you close the opening for a finished look when the pass-through isn't actively routing cable, or trim around cables already in place, keeping the rack's front or rear presentation clean for customer-facing or NOC environments.
• 20A/COMM rated opening: Sized and labeled specifically for 20-amp power circuits alongside communications cabling, so you're not guessing whether the opening is appropriate for a mixed power/data pass-through — it's built for that use case.
• TAA compliant: Meets Trade Agreements Act sourcing requirements, which matters directly for integrators bidding government, GSA, or federally funded institutional projects where TAA compliance is a hard procurement gate, not a nice-to-have.

Integration & Compatibility

The RC3CTCAL is designed as a rack accessory component within the Middle Atlantic catalog, intended to integrate with compatible rack and enclosure systems in the same product family. If you're planning a full rack build rather than a single accessory swap, it's worth reviewing a rack and enclosure planning guide before finalizing which cable management and pass-through components you need across the whole elevation, since power and communications routing choices made at one rack unit affect cable management decisions elsewhere in the same rack. For broader rack infrastructure needs, browse the full racks and enclosures category alongside complementary cable management accessories and rack power distribution components to round out a mixed power/data deployment.

Frequently Asked Questions

Q: Is the RC3CTCAL TAA compliant?

A: Yes, the RC3CTCAL is TAA compliant, which supports use on government and federally funded procurement projects with TAA sourcing requirements.

Q: What color is the RC3CTCAL flange?

A: The flange is finished in aluminum, with a black cover included for the opening.

Q: What is the RC3CTCAL rated for?

A: It's labeled as a 20A/COMM cable connector opening, sized for 20-amp power circuit and communications cable pass-through.

Q: Does the RC3CTCAL include a cover?

A: Yes, a black cover is included with the aluminum flange opening.

The RC3CTCAL is a small piece of hardware that solves a real problem on rack builds: a clean, finished 20A/COMM cable pass-through instead of an unfinished cut edge in the panel. It's an aluminum flange with a black cover, and that's the whole job — it does it well.

Technical Highlights:

• Aluminum flange: Rigid edge protection around the cable opening — no bare sheet-metal edge that can abrade cable jacketing during pulls or over time from vibration.
• 20A/COMM rating: The opening is specifically sized and labeled for 20-amp circuit runs sharing space with communications cabling, so you know it's appropriate before you cut into a panel.
• TAA compliance: Confirmed for this SKU, which matters on any federal or GSA-adjacent bid where sourcing compliance is a pass/fail line item.

Deployment Considerations:

• Confirm the RC3CTCAL's mounting footprint against your specific rack model before ordering — cable openings like this are typically built for a specific Middle Atlantic rack family rather than universal fit.
• The evidence available for this listing is limited to flange color, TAA status, and the 20A/COMM designation — if you need exact cutout dimensions or load specs beyond the 20A rating, confirm those against the rack elevation you're building before you commit the panel cut.

Reach for the RC3CTCAL when you're finishing out a rack elevation that mixes 20A power distribution with communications cabling in the same bay and want a factory-finished opening instead of a field-cut one — a common ask on NOC and data closet builds where the front-of-rack presentation matters as much as the wiring behind it.
