Middle Atlantic RC4CTCBS Poke-Thru Floor Box Communication Kit

Overview

The Middle Atlantic RC4CTCBS is a poke-thru floor box kit built around a 4-inch core drill opening, combining an Ortronics Series II Communication Housing with a set of Wiremold Open System unloaded adapters sized for 4 keystone jacks. It's a floor-penetration solution for conference rooms, trading floors, and open-office installs where power and low-voltage data need to come up through a slab rather than down a wall. RC4CTCBS ships as a commercial-grade assembly rated for both tile and carpet floor coverings, with a scrub water gasket already assembled at the factory — not a field add-on.

Key Features

• 4-inch (102mm) hole diameter: matches standard poke-thru core-drill specs, so you're not improvising a non-standard bit or hole saw on-site — plan the core drill to this dimension before the floor box arrives.
• Ortronics Series II Communication Housing: gives you a dedicated, separated data compartment inside the floor box rather than running comm cabling loose alongside power — keeps low-voltage and line-voltage segregated per typical code practice.
• Ortronics TracJack mounting adapters: the housing accepts TracJack-style modular jacks directly, so data ports snap into a known mounting pattern instead of requiring a custom faceplate cut.
• Wiremold Open System unloaded adapters (4 keystone): four open keystone positions let you field-populate the box with whatever mix of RJ45, fiber, or AV keystone modules the room actually needs, rather than being locked into a fixed factory configuration.
• Scrub water gasket, factory-assembled: the box is built to tolerate routine wet-mopping and floor-scrubbing without water intrusion into the electrical/data compartment — relevant for lobbies, conference centers, and any space cleaned with floor machines.
• 1/8-inch minimum floor covering thickness rating: confirms the flange is designed to sit flush with thin coverings like commercial carpet tile, so check your finished floor buildup against this minimum before ordering trim components.
• Rated for tile or carpet floors: one flange kit covers both common commercial floor finishes, simplifying spec across mixed-use buildings instead of stocking separate SKUs per floor type.
• TAA compliant: relevant for any installation tied to federal, state, or institutional procurement rules requiring Trade Agreements Act–compliant sourcing.

Integration & Compatibility

RC4CTCBS is built for installs already standardized on Ortronics TracJack connectivity and Wiremold Open System floor box hardware — it's not a universal poke-thru, so confirm your existing floor box shell and cover plate are from the same open system family before ordering. Because the communication housing keeps data separated from the power side of the poke-thru, this kit pairs naturally with structured cabling projects where the room also needs a nearby network video recorder or a PoE-fed edge device close to the floor penetration — plan conduit and cable runs accordingly during rough-in. For broader guidance on laying out floor and wall pathways ahead of a cabling contractor visit, see the PoE and low-voltage planning guide. If the room also carries surveillance or AV-over-IP infrastructure, review the IP camera catalog or PoE switch options to confirm rack and floor-box cable counts line up before the slab is core-drilled. The Middle Atlantic RC4CTCBS is best specified early in a room's electrical/data coordination — retrofitting a poke-thru after flooring is installed is a materially bigger job than planning it into the original floor plan.

Frequently Asked Questions

Q: What size hole does the RC4CTCBS require?

A: The RC4CTCBS is built for a 4-inch (102mm) core-drilled hole diameter.

Q: Does the RC4CTCBS work with carpet and tile floors?

A: Yes. It's rated for both tile and carpet floor coverings, with a minimum floor covering thickness of 1/8 inch.

Q: What data connectivity does the RC4CTCBS support?

A: It includes an Ortronics Series II Communication Housing with Ortronics TracJack mounting adapters and four unloaded Wiremold Open System keystone adapter positions, so keystone modules are field-installed to match the room's data requirements.

Q: Is the RC4CTCBS TAA compliant?

A: Yes, the RC4CTCBS is TAA compliant.

Q: What's the warranty on the RC4CTCBS?

A: The RC4CTCBS carries a 2-year warranty.

Q: Is the RC4CTCBS sealed against water from floor cleaning?

A: Yes, it ships with a scrub water gasket already assembled, intended for routine wet-mopping and floor-scrubbing environments.

The RC4CTCBS is one of those parts that only matters on the day you're standing over a core-drilled hole with the wrong-size housing in your hand — so get the 4-inch hole diameter confirmed against your drawings before the slab gets cut. This one's built around an Ortronics Series II Communication Housing, which is the detail that tells you it's meant for a data-heavy room, not just a power poke-thru.

Technical Highlights:

• 4-inch (102mm) hole diameter: a fixed core-drill spec — coordinate with the concrete contractor early since redrilling a poured floor isn't a same-day fix.
• 4 unloaded Wiremold Open System keystone adapters: you're not locked into a fixed jack count or type — populate all four with data, or mix in AV keystone modules depending on room use.
• Scrub water gasket, factory-assembled: rated for routine floor scrubbing, which matters in lobbies and conference centers cleaned with wet mop equipment on a schedule.

Deployment Considerations:

• Confirm the 1/8-inch minimum floor covering thickness against your actual finished floor buildup — thin luxury vinyl or bare concrete can fall under spec depending on the installer's flooring plan.
• Because the TracJack and Wiremold Open System adapters are proprietary to their respective product families, don't mix RC4CTCBS into a floor box program that's already standardized on a different open-system vendor — the adapters won't cross-fit.

Specify the RC4CTCBS for conference room and open-office floor poke-thrus where the room needs segregated power and data delivered mid-floor, the finish is carpet or tile, and the space gets routine wet-floor cleaning — a boardroom table drop or a trading-floor workstation cluster are the typical fits.
