Middle Atlantic AF Floorbox Black Tile CO - AF1-KT

Middle Atlantic AF1-KT Three-Gang Raised Floor Box with Black Flush Lid

Overview

The Middle Atlantic AF1-KT is a three-gang raised floor box designed for installations where clean, flush cable access matters as much as functionality — conference rooms, broadcast control suites, NOCs, and AV-integrated security operations centers. At 8.5 in wide × 5.25 in tall × 9.13 in deep (21.6 × 13.3 × 23.2 cm), the AF1-KT drops into standard raised-access flooring to deliver a recessed, three-position cable and connector interface that disappears into the floor surface when not in use. The flush black carpet-style lid blends with dark commercial flooring, reducing trip hazards and keeping the aesthetic clean in occupied spaces. If you've dealt with surface-mounted raceways in high-traffic AV or security rooms, this is the alternative that actually belongs in a finished installation.

The AF1-KT (often searched as AF1 KT) is TAA-compliant, satisfying federal procurement requirements for GSA schedules and government-funded projects. If your project carries a TAA mandate — common in federal buildings, DOD-adjacent facilities, and publicly funded infrastructure — this box qualifies without extra sourcing effort. For more options in the Middle Atlantic product line, including rack infrastructure and power management, the brand catalog covers most AV and security infrastructure needs.

Key Features

• Three-Gang Capacity: three discrete module positions in a single floor cutout — enough to accommodate power, data, and AV connectors side by side. That means one floor penetration instead of three, which matters when you're managing cable density under a raised floor or coordinating with a structural engineer on cutout placement.
• Flush Cover Style: the lid sits level with the surrounding floor surface when closed — no raised edges, no curled corners, no trip point in a working room. In a 24/7 security operations center or a broadcast studio where people move quickly in low light, flush-mount hardware is a real safety consideration, not a cosmetic one.
• Black Carpet-Style Lid Finish: the black finish is matched for dark commercial carpet environments — the kind you find in conference rooms, control rooms, and enterprise open-plan floors. It avoids the visual contrast that a bare metal lid creates, and it won't stand out against standard commercial flooring tile.
• Compact 8.5 × 5.25 × 9.13 in Footprint: the body fits the standard raised-floor tile cutout geometry. At 9.13 in deep, verify your plenum clearance before ordering — shallow plenums under 10 in may require a different box depth or a low-profile alternative in the AF series.
• TAA Compliance: verified TAA-compliant for this SKU, supporting procurement on GSA Schedule contracts and federally funded facility projects without additional country-of-origin documentation. If your RFP requires TAA, the AF1-KT checks that box explicitly.
• Raised-Floor Native Design: built specifically for raised-access flooring environments — the geometry, lid seating, and module bay layout are designed around the access-floor tile ecosystem rather than adapted from a surface-mount product. That matters for fit and finish when a facilities manager or general contractor does a final walkthrough.

Integration & Compatibility

The AF1-KT is part of Middle Atlantic's AF Series raised floor box line, designed to integrate with standard commercial raised-access flooring systems. The three-gang bay accepts compatible AV and data infrastructure modules — power inserts, data jacks, HDMI/DisplayPort keystone inserts, and similar panel-mount components — depending on the insert configuration you select separately. This modular approach means the box itself is a constant; the module population changes per room without swapping the floor hardware.

For security and AV integrators deploying in networked infrastructure environments, the AF1-KT provides a clean pathway for IP camera tails, PoE cable drops, and control system wiring in rooms where wall-mount conduit isn't an option. Pair it with appropriate strain-relief and cable management to keep the plenum organized under high-density flooring runs. For larger AV and security infrastructure planning, reviewing a structured cabling and infrastructure guide can help coordinate floor box placement with overall cable management strategy.

TAA compliance also makes the AF1-KT a natural fit alongside other TAA-verified access control and physical security hardware on federal and government facility projects where full procurement compliance is required at the component level.

Frequently Asked Questions

Q: Is the Middle Atlantic AF1-KT TAA-compliant?

A: Yes. The AF1-KT is verified TAA-compliant, making it eligible for GSA Schedule procurement and federally funded projects that require Trade Agreements Act compliance.

Q: What are the dimensions of the AF1-KT?

A: The AF1-KT measures 8.5 in wide × 5.25 in tall × 9.13 in deep (21.6 × 13.3 × 23.2 cm). Confirm your raised-floor plenum depth before installation — the box body requires at least approximately 9.13 in of clearance below the tile surface.

Q: What color is the AF1-KT lid?

A: The lid is black with a carpet-style finish, designed to blend with dark commercial flooring in conference rooms, control rooms, and similar occupied spaces.

Q: How many module positions does the AF1-KT provide?

A: Three gang positions, allowing you to populate the box with a combination of power, data, AV, or other panel-mount inserts in a single floor cutout.

Q: What type of floor is the AF1-KT designed for?

A: The AF1-KT is designed for raised-access flooring systems — the kind used in data centers, control rooms, broadcast facilities, and enterprise conference spaces. It is not intended for poured-concrete or standard slab floors without a raised-floor framework.

Q: Does the AF1-KT ship with module inserts?

A: The AF1-KT is the floor box and lid assembly. Module inserts (power, data, AV connectors) are selected and ordered separately based on your specific port configuration requirements.

The AF1-KT is the hardware you specify when the AV or security room design can't tolerate a surface raceway and the floor is raised-access — the 9.13 in body depth and three-gang bay solve the "where does the cable come up" problem cleanly, and the flush black lid means it won't be the first thing a client notices during a walkthrough. For TAA-mandated projects, this SKU is already on the compliant list, which saves the sourcing conversation with the GC or procurement officer.

Technical Highlights:

• Three-Gang Bay (8.5 in × 5.25 in body): three module slots in one 8.5 × 5.25 in footprint — one structural cutout, one box, full I/O flexibility. That's the right trade-off in a raised-floor room where every additional penetration is a coordination item.
• 9.13 in Installation Depth: the body extends 9.13 in below the tile surface. This is the measurement to check against your plenum spec before the box ships — a shallow plenum under 10 in is the most common fit issue on retrofit jobs.
• TAA Compliance (verified for AF1-KT): qualifies for GSA Schedule and federal facility procurement at the component level — useful when a project's compliance stack requires every installed item to carry its own TAA documentation, not just the major equipment.

Deployment Considerations:

• Measure plenum clearance before ordering — 9.13 in of body depth is the hard number. On retrofit jobs with older raised-floor systems, plenum heights vary by tile zone; check multiple points, not just one corner of the room.
• The AF1-KT ships as the box and lid assembly only — module inserts are specified separately. Factor insert lead times into your project schedule; the box can install ahead of insert availability, but the floor opening will need temporary cover if inserts are delayed.

Best-fit scenario: a new or renovated security operations center or enterprise conference room on raised-access flooring, where cable management discipline and TAA procurement compliance are both project requirements — the AF1-KT handles both without compromise.
