Middle Atlantic RC7CTCBS Poke-Thru Floor Box with 20A Power and Data

Overview

The Middle Atlantic RC7CTCBS is a multi-service poke-thru device that combines a 20A duplex receptacle with prewired data connectivity in a single floor-mounted assembly. It's built for conference rooms, open-office workstations, and AV integration points where power and data need to come up through the floor instead of running along a wall — the kind of installation where a surface raceway or wall plate simply isn't an option. The RC7CTCBS ships with a black cover and brushed brass flange, and the underlying frame accepts a 3 1/16'' (78mm) core-drilled hole, which is the standard bore size for this class of device.

Key Features

• 20A duplex receptacle: Rated for standard duplex or isolated-ground wiring, so it covers general office power as well as AV/data racks that need isolated ground to cut electrical noise on sensitive equipment.
• Prewired factory assembly: The unit arrives wired and ready to drop into the floor box, which cuts field labor compared to a knockdown kit an electrician has to wire on-site.
• Two Cat6 keystone connectors: Gives you two ready data drops at the same floor location as power — useful for a conference table or workstation cluster where you don't want a separate low-voltage penetration.
• Two Ortronics TracJack adapters: Lets you swap in Ortronics-brand keystone modules without buying a different faceplate — relevant if your data infrastructure standard is already built around Ortronics jacks.
• Two Wiremold Open System adapters: Adds compatibility with Wiremold's Open System keystone family, giving the install flexibility to mix connector brands as the AV or IT scope changes.
• Black flange and cover finish: A neutral, low-visibility finish for finished commercial floors — Middle Atlantic also offers the flange in gray or ivory paint, or brushed aluminum, if the black/brass combination doesn't match the room.
• 3 1/16'' (78mm) hole diameter: Matches standard core-drill sizing used across the poke-thru category, so an installer working from a typical drill template doesn't need a custom bore.
• 1/8'' minimum floor covering thickness: Confirms the device is rated to sit flush under carpet tile or thin flooring — check your finished floor buildup against this minimum before specifying.
• 4.00 lb assembled weight: Light enough for one installer to set and wire without rigging, which keeps floor-box installs on schedule in occupied buildings.

Integration & Compatibility

Because the RC7CTCBS includes both Ortronics TracJack and Wiremold Open System adapter plates alongside the two prewired Cat6 keystones, it slots into mixed-vendor structured cabling environments without forcing a single keystone brand on the whole job. That matters most in retrofit work, where the existing building standard for data jacks may not match what's in the box out of the parts room. The receptacle side supports standard duplex or isolated-ground wiring, so the same physical device works whether the circuit feeds general-purpose office power or an isolated-ground branch circuit for AV racks and conferencing gear that's sensitive to electrical noise. RC7CTCBS is TAA compliant, which is a relevant checkbox for government and federally funded commercial construction procurement.

For rooms that combine this floor power/data drop with ceiling or wall-mounted Middle Atlantic AV equipment, plan the conduit and cable pathway together rather than as separate trades — see the PoE and low-voltage planning guide for how to route floor, wall, and ceiling drops without conflicts. If the room also needs surveillance coverage, pair the data drops here with a nearby network video recorder location, and browse the broader AV accessories catalog for matching wall plates and raceway to finish the room. For distributed rack rooms feeding multiple floor boxes like this one, the VMS and rack architecture guide covers how to plan power and data backbone runs.

Frequently Asked Questions

Q: What size hole do I need to core-drill for the RC7CTCBS?

A: The device requires a 3 1/16'' (78mm) diameter hole.

Q: Does the RC7CTCBS support isolated-ground wiring?

A: Yes — the 20A duplex receptacle can be wired as standard duplex or isolated ground, depending on the circuit requirements.

Q: What data connectors come prewired with the RC7CTCBS?

A: It ships with two Cat6 keystone connectors, plus adapter plates for Ortronics TracJack and Wiremold Open System keystone modules.

Q: What's the warranty on the RC7CTCBS?

A: 1 year from installation, or 2 years from date of sale, whichever applies to your purchase.

Q: What floor thickness does the RC7CTCBS support?

A: A minimum floor covering thickness of 1/8'' is required.

Q: Is the RC7CTCBS TAA compliant?

A: Yes, it is listed as TAA compliant.

The Middle Atlantic RC7CTCBS is one of those devices you spec once at the drawing stage and never think about again — until the core-drill dimension is wrong and the floor's already poured. It's a 20A duplex poke-thru with two prewired Cat6 keystones, sized for a 3 1/16'' (78mm) hole.

Technical Highlights:

• 20A duplex, standard or isolated ground: One receptacle spec covers both general office circuits and isolated-ground AV/rack circuits, so you don't need to stock two versions of this device for different room types.
• Dual keystone adapter compatibility (Ortronics TracJack + Wiremold Open System): On a retrofit where the building's existing jack standard doesn't match what's in your parts bin, this saves a return trip to the supply house.
• 1/8'' minimum floor covering thickness: A small number, but it's the number that determines whether this device sits flush under your specified carpet tile — check it against the finish schedule before ordering.

Deployment Considerations:

• Confirm the 3 1/16'' (78mm) core-drill dimension against your floor box template before the concrete work starts — this is a fixed hole size, not a field-adjustable one.
• The unit ships prewired at 4.00 lbs, which is light enough for a single installer to set and terminate, but verify your isolated-ground circuit is landed correctly at the panel before energizing — the receptacle supports either wiring scheme, it doesn't self-configure.

RC7CTCBS is the right call for a conference-table or open-office floor drop that needs both a 20A circuit and two data ports in one clean penetration — not a fit for a job that only needs power or only needs data, where a simpler single-service poke-thru will cost less.
