Middle Atlantic RC4CTCAA Poke-Thru Floor Box with Aluminum Slide Holder

The RC4CTCAA is a multi-service poke-thru floor box from the Middle Atlantic Middle Atlantic catalog, built around a 4-inch (102mm) core-drilled opening and finished with a nonmetallic aluminum-colored (AA) slide holder. It's the connectivity path integrators run when power and communication cabling both need to surface from a finished floor — conference tables, trading desks, huddle rooms, broadcast studios — without leaving a raised box or exposed conduit run in the room. RC4CTCAA ships in the standard flange/cover configuration and pairs with Middle Atlantic's Series II communication housing for a finished, code-compliant floor termination.

Overview

This is a passive infrastructure product, not an active device — it's the physical housing and finish flange that lets AV and network cabling exit a concrete or raised floor cleanly. RC4CTCAA is rated for both carpet and tile floor coverings, with a minimum covering thickness of 1/8 inch, so the same part number works across most finished-floor conditions an integrator hits on a commercial buildout. At 3.00 lbs, it's a straightforward single-technician install once the core hole is cut.

Key Features

• 4'' (102mm) hole diameter: matches standard core-drill bit sizing used on commercial floor poke-thru jobs, so you're not hunting for a nonstandard drill or reducer ring on site.
• Carpet and tile floor compatibility: one part covers the two most common finished-floor types in office and conference environments, cutting the SKUs you need to stock for a multi-room rollout.
• Min 1/8'' floor covering thickness: confirms the flange seats properly on standard-gauge carpet tile or resilient flooring — check thicker luxury vinyl or stone tile against this spec before ordering.
• Ortronics Series II Communication Housing: gives the poke-thru a defined data/comm cavity separate from the power side, which matters for maintaining separation between low-voltage and line-voltage runs inside the same floor box.
• Wiremold Open System and Ortronics TracJack adapter support: lets you standardize on either adapter ecosystem for the comm side depending on what's already specified in the building's low-voltage plan, instead of being locked to one connector family.
• Assembled scrub water gasket: ships pre-installed rather than as a loose part, so the floor box is ready for wet-mopped or scrubbed commercial floors (lobbies, cafeterias) without a separate gasket-fitting step.
• Nonmetallic aluminum-colored (AA) slide holder: the RC4CTCAA configuration specifically, distinguishing it from the AB (brass-colored) slide holder variant in the same family — match this to the room's hardware finish before specifying.
• Multiple finish options (painted gray, black, ivory, brushed aluminum, brass): the flange finish can be matched to flooring or fixture color on the broader RC4CT platform, giving architects and integrators a finish path that doesn't stand out against the floor.
• Slide cover in gray, black, ivory, or black AL/BS default: the sliding access cover comes in options to blend with the finish flange rather than forcing a mismatched cover color.

Integration & Compatibility

RC4CTCAA's comm-side adapter compatibility (Wiremold Open System, Ortronics TracJack) means it slots into floor-based cabling plans that are already standardized on those connector systems — a common scenario when the poke-thru feeds a conference table that also needs rack and power distribution gear elsewhere in the room. Because the comm and power paths are handled as separate cavities inside the Series II housing, this isn't a device you configure — it's a mechanical termination point, so plan the low-voltage and line-voltage cable runs into the box before the core is drilled. For AV and network rooms where this floor box feeds a rack, review a PoE and cable planning guide to size conduit and cable count correctly before the floor is opened. If the room also needs surface-mounted mounting accessories for equipment above the floor, plan those alongside the poke-thru during the same design pass.

Frequently Asked Questions

Q: What size hole does the RC4CTCAA require?

A: The RC4CTCAA is built around a 4-inch (102mm) diameter core-drilled opening.

Q: Is the RC4CTCAA rated for carpet or tile floors?

A: Both. It's compatible with carpet and tile floor coverings with a minimum covering thickness of 1/8 inch.

Q: What's the warranty on the RC4CTCAA?

A: Middle Atlantic backs the RC4CTCAA with a 2-year warranty.

Q: What slide holder finish does the RC4CTCAA come with?

A: The RC4CTCAA configuration uses a nonmetallic aluminum-colored (AA) slide holder. A brass-colored (AB) version exists elsewhere in the same product family.

Q: What connector adapters does the RC4CTCAA support?

A: The comm housing supports Wiremold Open System and Ortronics TracJack adapters.

Q: How much does the RC4CTCAA weigh?

A: 3.00 lbs.

The detail that matters on the RC4CTCAA is the 4-inch core-drill opening — that's the number your electrician needs before anyone shows up on site with a core bit, and it's not negotiable once the concrete's cut. This is the aluminum slide holder (AA) configuration, and it's a mechanical part, not an active one, so the spec sheet is short but every line on it affects the install.

Technical Highlights:

• 4'' (102mm) hole diameter: standard core-drill sizing means no custom bit rental and no reducer adapters to source separately.
• Carpet/tile compatibility, min 1/8'' covering thickness: covers the two dominant finished-floor types on commercial jobs, but verify your floor covering meets that 1/8'' minimum before you spec this over a thin resilient product.
• Ortronics Series II Communication Housing with Wiremold Open System and TracJack adapter support: gives you two adapter ecosystems to standardize the comm side on, which keeps the RC4CTCAA usable whether the building's low-voltage plan is already Wiremold- or Ortronics-based.

Deployment Considerations:

• The scrub water gasket ships assembled, not loose — one less step during install, and it means the box is ready for wet-mopped commercial floors (lobbies, cafeterias, trading floors) out of the box.
• The AA slide holder is aluminum-colored specifically — if the room's hardware runs brass tone instead, you want the AB variant in the same family, not this part number.

Spec RC4CTCAA for conference-room and trading-desk floor poke-thrus where the table needs both power and structured cabling to surface through a finished carpet or tile floor, and where the building's comm plan is already standardized on Wiremold or Ortronics TracJack hardware.
