Middle Atlantic RC3CTCBS Brass Flange 20A/Comm Cover Plate

The RC3CTCBS from Middle Atlantic is a connector cover plate finished with a brass flange, built for 20A power and communications cutouts inside rack and enclosure systems. Manufacturer data on this specific part is limited, so treat the notes below as a starting point rather than a full spec sheet — confirm exact cutout dimensions and mounting pattern against your rack layout before ordering.

Overview

Middle Atlantic's connector and cable-management accessories are built to close out unused or repurposed cutouts on rack rails, panels, and enclosures cleanly, and the RC3CTCBS fits that role for a 20A/communications combo opening. The part is TAA-compliant, which matters if you're speccing this into a government, education, or federally-funded integration where sourcing rules apply.

Key Features

• Brass flange finish: a durable, commercial-grade surface finish that holds up better than painted or plastic covers in racks that get opened and closed repeatedly during service.
• 20A/communications cutout compatibility: matches a combined power-and-data cutout pattern, so you're not stacking two separate blank plates or improvising a cover on a mixed-use opening.
• TAA-compliant sourcing: qualifies for integrations that require Trade Agreements Act compliance, which is a hard requirement on many government and institutional bids.

Integration & Compatibility

This cover plate is intended to pair with Middle Atlantic rack and enclosure hardware sharing the same 20A/communications cutout pattern. Because manufacturer dimensional data wasn't available at the time of writing, verify cutout size and screw pattern against your existing rack elevation or Middle Atlantic's own documentation before finalizing a build-out — that's the one variable worth double-checking on any cover plate order.

The RC3CTCBS is one of those parts that only shows up on a BOM when you're closing out a rack build correctly instead of leaving an open cutout behind a patch panel. It's a brass-flange cover for a 20A/communications combo opening — small part, but it's the difference between a finished rack elevation and one with a gap an installer has to explain later.

Technical Highlights:

• Brass flange: holds a clean commercial-grade finish through repeated rack service better than a painted stamped-steel cover.
• 20A/comm combo cutout: covers a mixed power-and-data opening in one plate instead of requiring two separate blanks.
• TAA compliance: confirmed compliant, which is the gating spec on most public-sector rack build-outs.

Deployment Considerations:

• Confirm the cutout pattern against your specific rack or enclosure model before ordering — Middle Atlantic runs several cutout families and this one is sized for the 20A/comm combo opening specifically.
• Full dimensional and mounting spec sheets weren't available for this listing, so treat this as a fit-check item rather than a spec-driven selection.

Reach for the RC3CTCBS when you're closing out a Middle Atlantic rack build that has an unused 20A/communications cutout and TAA compliance is a bid requirement — it's a finishing-hardware pick, not a headline spec item.
