Middle Atlantic 4ATCP2RBK Prewired Surface Poke-Thru Device

Overview

The Middle Atlantic 4ATCP2RBK is a prewired, single-duplex surface poke-thru floor device from the 4AT Evolution line — built for conference rooms, boardrooms, training spaces, and open-plan environments where power and signal access needs to come up through the floor cleanly and stay accessible at table or desk level. The surface cover style keeps the device above the floor plane, making it the right pick when flush-recessed installation isn't practical or when the floor construction doesn't permit a fully recessed fit.

Middle Atlantic's poke-thru and AV infrastructure products are designed for integrators who need reliable, repeatable installations — and the 4ATCP2RBK ships prewired, which cuts field labor compared to field-assembled alternatives. If you're specifying AV infrastructure for commercial spaces, this model is worth evaluating anywhere a single duplex outlet at floor or table level is the requirement.

Key Features

• Prewired from the factory: The 4ATCP2RBK arrives fully prewired, eliminating the time typically spent assembling and terminating the outlet module on-site. For integrators running multiple drops in a single installation, this is a real labor savings — no additional termination steps at the device level.
• Single duplex outlet: One duplex receptacle per unit. If your table or floor location only needs two power positions, this is the right fit. Specifying a larger unit for a single-outlet requirement wastes budget and floor real estate. Match the outlet count to the actual load.
• Surface cover style: The surface mount profile sits above the finished floor, which works well in concrete slab or raised-floor environments where cutting for a fully recessed installation isn't feasible. It's also a faster install in retrofit scenarios — less floor modification required.
• Black finish: The 4ATCP2RBK ships in black, which integrates cleanly into dark conference table and flooring environments without the visual contrast of a brushed aluminum or white cover. Confirm the finish matches your interior specification before ordering.
• Compact body dimensions (5.5" H x 5.5" W): The 5.5" x 5.5" body keeps the floor footprint tight — relevant in high-traffic areas where a wide device creates a tripping hazard or conflicts with furniture placement.
• Overall assembled dimensions 21" x 8.25" x 8.25": The full 21-inch length includes the conduit body and cover assembly. Verify your floor cavity and below-slab clearance accommodates this depth before scheduling the installation — insufficient below-floor depth is the most common field problem with poke-thru devices.
• 18.56" installation depth: At 18.56 inches (47.1 cm) of required depth below the finished floor, this device is engineered for standard commercial floor-to-ceiling plenum depths. Measure your actual slab-to-subfloor or access floor depth before committing — this spec determines whether the unit physically fits.

Integration & Compatibility

The 4ATCP2RBK is designed for commercial office, conference, and AV integration environments. As part of the Middle Atlantic 4AT Evolution series, it is compatible with the broader 4AT ecosystem of inserts and cover configurations. Coordinate with your power distribution planning to confirm circuit loading against the single duplex capacity — one duplex means two receptacle positions on a shared circuit. For multi-outlet requirements at the same floor location, evaluate higher-outlet-count variants in the 4AT Evolution line rather than deploying multiple single-duplex units side by side.

Frequently Asked Questions

Q: What does the 18.56-inch depth spec mean for installation planning?

A: The 18.56 inches (47.1 cm) is the required clearance below the finished floor surface for the device body. Before installation, measure your available below-floor depth — concrete slab, raised access floor cavity, or plenum space — to confirm the unit fits. This is the most common field issue with poke-thru devices and must be verified before rough-in.

Q: Is the 4ATCP2RBK fully prewired, or does it require field termination?

A: The 4ATCP2RBK is factory prewired. The duplex outlet module comes assembled and terminated from the factory, reducing field labor at the device level. You will still need to make the incoming circuit connection per local electrical code.

Q: What is the cover style on the 4ATCP2RBK, and when is surface style appropriate?

A: The 4ATCP2RBK uses a surface cover style, meaning the cover sits above the finished floor rather than flush with it. This is appropriate when the floor construction doesn't allow a fully recessed cut-out, in retrofit scenarios where floor modification is impractical, or in raised access floor environments where the surface profile is acceptable.

Q: How many outlets does the 4ATCP2RBK provide?

A: One duplex receptacle — two outlet positions on a shared circuit. If your floor location requires more receptacles, evaluate higher-outlet-count variants in the 4AT Evolution family rather than stacking multiple single-duplex units.

Q: What is the body footprint of the 4ATCP2RBK at the floor surface?

A: The device body measures 5.5 inches wide by 5.5 inches tall. The overall assembly including conduit body and cover is 21 inches x 8.25 inches x 8.25 inches (533.4 x 209.6 x 209.6 mm). Confirm furniture clearances and traffic paths accommodate this footprint before finalizing the floor drop location.

Marty Allison

The 4ATCP2RBK is a purpose-built floor infrastructure device and the spec I always check first on any poke-thru is the required installation depth — at 18.56 inches (47.1 cm), this unit demands meaningful below-floor clearance, and I've seen installs stall because the slab-to-subfloor gap came in short. Verify that measurement before anything else goes on the schedule.

Technical Highlights:

• Prewired configuration: Factory-terminated duplex module means no field assembly at the device level — real time savings across a multi-drop conference room or training suite build-out.
• Surface cover profile: Designed for above-floor mounting rather than flush-recessed, making it the correct choice on concrete slab or in retrofit scenarios where core drilling for a recessed device isn't practical.
• Compact 5.5" x 5.5" body: Tight footprint keeps the floor-level obstruction minimal — important in any high-foot-traffic room where a wide device becomes a trip hazard or conflicts with chair movement.

Deployment Considerations:

• Confirm the full 18.56-inch depth is available below the finished floor before rough-in — this is the single most common field problem with poke-thru devices and is non-negotiable once the install is scheduled.
• One duplex means two receptacle positions total. If the table position needs more than two power connections, spec a higher-outlet-count 4AT Evolution variant rather than clustering multiple 4ATCP2RBK units at the same floor location.

This device is well-suited for conference room and training facility builds where single-point floor power access is the requirement and surface-profile installation is acceptable — particularly in retrofit projects where recessed poke-thru installation is impractical.
