Middle Atlantic RC4 PT W/ BK Flange AND BK Center - RC4ATCBK

Middle Atlantic RC4ATCBK Poke-Thru Floor Assembly — Black Flange and Center

Overview

The Middle Atlantic RC4ATCBK is a surface-style, multi-service poke-thru floor assembly finished in black, with a black flange and black center. Designed for commercial floor installations where you need a clean, managed pathway for power, data, and AV services through finished flooring — without exposed conduit runs or wall-chased cabling. The RC4ATCBK measures 8.25" wide × 8.25" tall × 16.38" deep, giving installers a predictable rough-in footprint in concrete or raised-access flooring environments.

TAA compliance is confirmed for this SKU, making the RC4ATCBK eligible for federal government, defense agency, and public-sector projects subject to the Trade Agreements Act procurement requirements. If your project spec sheet calls for TAA-compliant floor infrastructure, this unit satisfies that gate without substitution.

Key Features

• Black Flange and Black Center Finish: The all-black color scheme integrates cleanly into dark-flooring commercial spaces — conference rooms, boardrooms, command centers — where a chrome or aluminum finish would draw unwanted visual attention to the floor outlet location.
• 16.38-Inch Installation Depth: At 16.38" (41.6 cm) deep, the RC4ATCBK accommodates typical commercial concrete slab depths and standard raised-floor plenum clearances. Verify your slab or plenum depth before ordering — undersized cavities require a different cut depth variant.
• 8.25" × 8.25" Footprint: The square 8.25" × 8.25" body fits standard RC4-family cutout templates. If you are replacing an existing RC4 poke-thru or working from a pre-cut slab, this unit drops into the same rough opening without re-coring.
• TAA Compliant: Verified TAA compliance for this SKU supports procurement on GSA schedules and federally funded construction projects where country-of-origin restrictions apply.
• Surface-Style Assembly: The surface-style design sits at finished floor level rather than recessing below grade, simplifying installation in environments where sub-floor depth is limited or where future serviceability is a priority.

Integration and Compatibility

The RC4ATCBK is part of Middle Atlantic's Middle Atlantic poke-thru and floor box line, designed to accept RC4-family inserts and service modules. It is suited for AV and structured cabling infrastructure deployments in commercial interiors. Consult your cable management planning resources when routing service bundles through the floor core — bundle diameter and service count will determine whether you need additional pathways alongside the primary assembly. For projects involving power distribution at the floor level, pair with compatible power modules rated for the load and circuit configuration your design requires.

Frequently Asked Questions

Q: Is the RC4ATCBK TAA compliant?

A: Yes. TAA compliance is confirmed for the RC4ATCBK, making it eligible for federal, defense, and public-sector projects subject to Trade Agreements Act procurement requirements.

Q: What are the installation depth requirements for the RC4ATCBK?

A: The RC4ATCBK has a body depth of 16.38 inches (41.6 cm). Verify that your concrete slab or raised-floor plenum provides at least this clearance below the finished floor surface before ordering.

Q: What finish color is the RC4ATCBK?

A: The RC4ATCBK ships with a black flange and black center. If your project requires a different finish, check for other RC4 family variants in the Middle Atlantic lineup.

Q: What is the footprint of the RC4ATCBK?

A: The body measures 8.25 inches wide by 8.25 inches tall (21 cm × 21 cm). Shipping dimensions are 8.63" × 8.63" × 16.68".

Q: Can the RC4ATCBK be used on GSA schedule procurements?

A: TAA compliance is confirmed for this SKU, which is a prerequisite for GSA schedule and many federally funded construction procurements. Confirm with your contracting officer that all other schedule requirements are met.

Marty Allison

The RC4ATCBK is a purpose-specific unit — if you need a TAA-compliant black poke-thru for an RC4-family cutout at 16.38" installation depth, this is the part. Where I see it specified most often is in conference room AV refreshes and government facility fit-outs where the floor infrastructure has to satisfy both aesthetic and procurement requirements simultaneously.

Technical Highlights:

• 16.38" Installation Depth: This is the spec that controls whether the unit physically fits your floor assembly. At 41.6 cm, it handles most standard commercial slab thicknesses — but measure your plenum or core depth before the purchase order, not after.
• 8.25" × 8.25" Body: Square footprint maps directly to RC4-family rough-in templates. If the slab is already cored for an RC4, this drops in without modification.
• TAA Compliance: Confirmed on this SKU — not assumed. On government and defense projects, TAA compliance at the component level is a hard procurement gate, and having it documented on a poke-thru assembly saves the submittal process a round-trip.

Deployment Considerations:

• Confirm slab or plenum clearance of at least 16.38" before specifying this unit — the depth is fixed and there is no field-adjustable trim on the assembly length.
• The all-black finish (flange and center) is a deliberate aesthetic choice. If the surrounding flooring is light-colored or if the AHJ requires a high-contrast floor outlet marker for accessibility, a different finish variant may be more appropriate.

Best fit: government facility AV infrastructure, corporate conference room floor-outlet installations, and any project where TAA documentation is a hard line-item on the submittal checklist.
