Middle Atlantic Flush Poke-thru ASSY/20A/ - RC3ATCBS

Middle Atlantic RC3ATCBS Flush Poke-Thru Assembly

The Middle Atlantic RC3ATCBS is a multi-service assembled flush poke-thru device designed for routing power and low-voltage data or AV connections through floors and work surfaces in commercial installations. At 7.5 in × 7.5 in with a 16-inch depth, it fits standard floor-box cutouts in raised access flooring, concrete, or wood decking without requiring a custom rough-in. The brass finish makes it a practical choice for conference rooms, boardrooms, and executive spaces where the floor or surface fitting needs to match architectural hardware rather than disappear into a utility gray box.

TAA compliance is verified for this SKU — relevant for federal government facilities, GSA contract work, and any project with a Buy American or Trade Agreements Act requirement written into the spec. If your project has a TAA clause, the RC3ATCBS satisfies it; confirm with your contracting officer as project requirements vary.

Key Features

• Flush Poke-Thru Form Factor: Mounts flush with the finished floor or surface — no raised lip to catch foot traffic or rolling equipment, which matters in high-pedestrian commercial spaces like conference centers and open-plan offices.
• 7.5 in × 7.5 in Footprint: Fits standard multi-service poke-thru cutout dimensions, minimizing core drilling scope and allowing drop-in replacement of same-family units during renovation without re-cutting the slab.
• 16-Inch Depth: Provides sufficient below-deck clearance for routing cables from the floor cavity to the surface inserts — accommodates typical raised-floor plenum depths and standard wood-frame or concrete floor assemblies.
• Brass Finish: Coordinates with architectural hardware in premium commercial interiors. Where a stainless or black finish would read as utilitarian, brass integrates with hospitality, legal, and executive environments without a secondary cover plate.
• TAA Compliant: Verified TAA compliance for this SKU supports procurement on federal, state, and municipal projects with domestic-sourcing requirements — no waiver paperwork needed for this line item.
• Assembled Configuration: Ships as a complete assembly — the RC3ATCBS arrives ready for rough-in, reducing field labor compared to specifying inserts and the housing separately and assembling on-site.

Integration & Compatibility

The RC3ATCBS belongs to Middle Atlantic's RC3ATC multi-service poke-thru family. Poke-thru devices in this family are typically coordinated with the building's electrical rough-in and low-voltage pathway design — verify the floor or deck substrate thickness and plenum clearance against the 16-inch depth before ordering. For Middle Atlantic infrastructure products on the same project, confirm insert configurations with the AV or electrical engineer of record, as insert modules for power, data, and AV vary by project spec and are typically selected separately or as part of the assembled unit's configuration.

For projects specifying floor cable management across multiple zones, poke-thru placement should be coordinated with furniture layout and power distribution to avoid daisy-chaining extension cords from a single point — each poke-thru is a dedicated pathway, not a distribution hub. Pair with appropriate AV infrastructure for a complete floor-to-surface signal and power pathway.

Frequently Asked Questions

Q: Is the RC3ATCBS TAA compliant?

A: Yes. TAA compliance is confirmed for this SKU, making it eligible for federal, state, and municipal projects with Trade Agreements Act requirements.

Q: What are the dimensions of the RC3ATCBS?

A: The RC3ATCBS measures 7.5 in wide × 7.5 in tall with a 16-inch depth (40.6 cm deep, 19.1 cm × 19.1 cm face).

Q: What color/finish does the RC3ATCBS come in?

A: Brass. It's designed for architectural environments where finish coordination with hardware is part of the specification.

Q: Is the RC3ATCBS pre-assembled or does it require field assembly of inserts?

A: The RC3ATCBS is described as an assembled poke-thru device. Confirm specific insert configuration with the project specification or the manufacturer's product documentation, as multi-service assemblies can vary by configuration.

Q: What floor or deck types is this suitable for?

A: The 16-inch depth accommodates standard raised-access flooring and concrete or wood-frame deck assemblies. Verify substrate depth and clearance requirements against your specific installation conditions before procurement.

The RC3ATCBS is one of those spec items that looks straightforward on paper — a 7.5 × 7.5 inch flush poke-thru in brass — but the decisions that matter happen before the order is placed. The 16-inch depth is the number I always check first on any poke-thru spec: if the deck or raised floor cavity is shallower than that, you're re-specifying on-site, which costs more than getting it right at bid time.

Technical Highlights:

• 16-Inch Depth: Defines the minimum below-surface clearance needed — measure your plenum or deck cavity before committing. Concrete slab with a thin raised floor? Confirm total depth including the subfloor void.
• 7.5 × 7.5 in Face: Standard multi-service poke-thru footprint means this drops into existing cutouts on retrofit projects without re-coring — a real labor-cost lever on occupied-space renovations.
• TAA Compliant: Verified for this SKU — useful on government or institutional projects where a single non-compliant line item can stall procurement. No additional documentation chase needed for this part.

Deployment Considerations:

• Brass finish is an architectural choice, not just cosmetic — specify it intentionally for boardrooms and hospitality spaces; if the rest of the hardware is stainless or black, order accordingly and don't assume finishes can be swapped post-delivery.
• Assembled poke-thrus ship with a defined insert configuration — if the project AV or electrical spec calls for a specific power/data/AV insert mix, confirm the assembly matches before procurement rather than discovering a mismatch during rough-in.

Best fit for a conference room or executive suite retrofit where the contractor needs a TAA-compliant, architecturally finished floor service point that drops into an existing cutout — not a blank-slate new construction where insert flexibility might push you toward a configurable housing instead.
