Middle Atlantic Flush Poke-thru ASSY/20A/ - RC3ATCBK

Middle Atlantic RC3ATCBK Flush Poke-Thru Multi-Service Assembly

Overview

The Middle Atlantic RC3ATCBK is a flush-mount, multi-service poke-thru device designed to bring power and low-voltage signal connections up through a floor surface in a clean, finished enclosure. At 7.5 in × 7.5 in with a 16-inch depth, it accommodates the plenum clearance and conduit routing typical of commercial conference rooms, boardrooms, and open-plan AV integration projects. Its black finish blends with dark floor box trim standards common in corporate and government interiors. TAA compliance makes the RC3ATCBK a direct fit for federally funded installations and government-contract AV/IT projects where procurement rules require US trade agreement conformance.

Poke-thru devices occupy a narrow but critical niche in Middle Atlantic's infrastructure lineup — they are the last-mile connection point between the building's in-floor conduit system and the work surface or conference table above. Getting this spec wrong means a torn-up floor or an exposed adapter that fails inspection. The RC3ATCBK solves that problem with a fully assembled unit that ships ready to drop into a core-drilled opening.

Key Features

• Flush-Mount Form Factor (7.5 in × 7.5 in footprint): The square 7.5-inch face plate fits standard core-drill openings used in most commercial slab construction. A flush finish means no trip hazard and no raised lip that catches chair wheels — relevant in any high-traffic meeting or collaboration space.
• 16-Inch Installation Depth: The 16 in (40.6 cm) depth provides adequate clearance to route conduit, pull wire, and terminate connections inside the floor cavity without cramping. This matters in thick concrete slab construction where shallower units force tight bends that damage cable jackets.
• 20-Ampere Circuit Rating: Rated for 20A service, the RC3ATCBK supports a full 20A branch circuit — enough headroom to power a conference room's AV stack, laptop charging, and display without splitting across multiple floor boxes. A 15A-rated unit would require load balancing that adds design complexity.
• Multi-Service Configuration: Designed to carry both power and low-voltage (AV, data, or telecom) in a single floor opening. Combining services in one box reduces the number of core-drill penetrations, which lowers both installation cost and structural impact on the slab.
• Black Color Finish: The black trim integrates with dark-toned flooring and furniture systems common in modern commercial interiors. Specifying the correct color at the time of order avoids a visible mismatch that is difficult to correct post-installation without replacing the cover plate.
• TAA Compliant: Verified TAA (Trade Agreements Act) compliance means the RC3ATCBK qualifies for GSA schedule purchases, federal agency deployments, and any contract requiring domestic or TAA-designated country of origin. This is a hard procurement gate on many government and higher-education projects — non-compliant hardware gets rejected at the purchasing stage regardless of technical fit.
• Fully Assembled Unit: Ships as a complete assembly, not a kit. Field assembly of poke-thru components introduces torque inconsistency and misalignment risk. A factory-assembled unit arrives with consistent mechanical tolerances and reduces on-site labor time.

Integration & Compatibility

The RC3ATCBK is part of Middle Atlantic's poke-thru and floor box product line, designed to integrate with standard commercial conduit infrastructure. The 7.5 × 7.5 in footprint is compatible with common core-drill tooling used by commercial electrical contractors. For AV integrators specifying complete conference room AV infrastructure, this unit pairs with in-wall and in-ceiling cable management pathways to deliver a fully concealed signal and power distribution system. Installers working on rack and enclosure projects that extend to furniture-level connectivity will find the RC3ATCBK a logical endpoint for structured wiring runs originating at a wall rack or credenza enclosure. Confirm the floor cavity depth at the installation site before ordering — 16 inches of required depth can be a constraint in raised-access floor environments with shallow plenum clearance.

Frequently Asked Questions

Q: Is the RC3ATCBK TAA compliant?

A: Yes. The RC3ATCBK is verified TAA (Trade Agreements Act) compliant, making it eligible for GSA schedule procurement, federal agency projects, and contracts that require TAA-designated country of origin.

Q: What is the amperage rating of the RC3ATCBK?

A: The RC3ATCBK is rated for 20-ampere service, supporting a full 20A branch circuit for power and low-voltage multi-service applications.

Q: What are the physical dimensions of the RC3ATCBK?

A: The RC3ATCBK measures 7.5 inches wide × 7.5 inches tall with a 16-inch installation depth (40.6 cm deep). Confirm your floor cavity depth before ordering.

Q: Does the RC3ATCBK support both power and low-voltage connections?

A: Yes. It is a multi-service assembly designed to carry both power (20A) and low-voltage services — such as AV, data, or telecom — through a single floor opening.

Q: What color is the RC3ATCBK?

A: The RC3ATCBK ships in black. Verify the color specification at order time — replacing a cover plate post-installation requires pulling the unit or ordering a separate trim kit.

Q: Does the RC3ATCBK ship fully assembled?

A: Yes. It is a factory-assembled unit, not a field-assembly kit, which reduces installation labor and ensures consistent mechanical tolerances.
