Middle Atlantic NM Flex Pancake 10FT.140 - BK1400-10

Middle Atlantic BK1400-10 Non-Metallic Pancake Over-Floor Raceway

The Middle Atlantic BK1400-10 is a 10-foot, non-metallic pancake over-floor raceway designed to route and protect low-voltage cables across finished floors without tearing up the surface or creating a trip hazard. At just 0.63 inches tall and 3 inches wide, this black raceway sits flat enough to slide under most door clearances and lays flush against hard flooring — the kind of clean, permanent-looking solution that matters on a final walkthrough. If you've ever had to justify a cord running across a conference room floor or a camera cable crossing a lobby, the BK1400-10 is the product that closes that conversation.

Overview

Part of the Middle Atlantic cable management line, the BK1400-10 belongs to the NM Flex Pancake series — a family of non-metallic over-floor raceways built for permanent low-voltage installations in commercial environments. The non-metallic construction keeps the profile ultra-low while remaining durable enough for foot traffic in light-to-moderate commercial spaces. The 10-foot run length — 3.1 meters exactly — covers a full room width in most standard office, retail, or security installations without a mid-run splice. TAA compliance means the BK1400-10 qualifies for U.S. government projects and federally funded procurements where the Trade Agreements Act applies, a requirement that disqualifies a lot of otherwise-comparable commodity cord covers.

Key Features

• 0.63-inch profile height: At under two-thirds of an inch tall, the BK1400-10 clears most commercial door sweeps and thresholds without modification — you won't be shimming doors or calling back to adjust clearances. That 1.6 cm height also means the transition ramp is gradual enough to meet ADA threshold guidance for floor-level obstructions in most jurisdictions.
• 3-inch channel width: The 3-inch (7.6 cm) interior accommodates multiple low-voltage runs side by side — a camera drop cable, a PoE patch lead, and a control wire can share the raceway without bundling them into a single crush point. This matters for security and AV integrators who need separation between signal types.
• 10-foot single-piece run: A single 10 ft (3.1 m) section spans most standard commercial room widths without a mid-run joint. Fewer joints mean fewer failure points, cleaner aesthetics, and faster installation — particularly relevant on polished concrete or tile where adhesive positioning is a one-shot process.
• Non-metallic construction: The NM material eliminates galvanic corrosion concerns and prevents the raceway from acting as a ground path — an important detail when routing low-voltage signal cables in facilities where ground loops cause interference in camera or audio feeds. Non-metallic also means no sharp edges from field cuts.
• Black finish: The factory black color blends into dark hardwood, rubber flooring, and most commercial carpet tile borders without painting or wrapping. For installations where the raceway will be visible, color-matching from the factory eliminates a field finishing step.
• TAA Compliant: Verified TAA compliance makes the BK1400-10 eligible for GSA schedules and government-funded projects where country-of-origin restrictions apply. If your project has a TAA clause in the spec — and most federal, state, and DoD installs do — this is the line item that keeps the job compliant without substituting product.

Integration & Compatibility

The BK1400-10 is designed to work within the broader Middle Atlantic raceway ecosystem. It pairs naturally with matching end caps, couplers, and reducer fittings from the NM Flex Pancake family, allowing multi-section runs and clean terminations at wall bases. For security camera cable management, the 3-inch channel width accommodates standard Cat6 patch leads, RG59 coax, and 18/2 power runs simultaneously — relevant for hybrid analog/IP camera transitions where both cable types may coexist in the same run. The non-metallic body is compatible with field cutting using standard utility or miter saws, allowing custom lengths without specialized tooling. When used alongside surface-mount conduit or wall raceway systems, the BK1400-10 connects the vertical wall drop to the horizontal floor run, completing a fully enclosed cable path from PoE switch or NVR to the camera or device endpoint.

Frequently Asked Questions

Q: Is the BK1400-10 TAA compliant?

A: Yes. The BK1400-10 is verified TAA compliant, making it eligible for U.S. government contracts, GSA schedule projects, and federally funded installations where Trade Agreements Act compliance is required.

Q: What are the exact dimensions of the BK1400-10?

A: The BK1400-10 is 10 feet (3.1 m) long, 3 inches (7.6 cm) wide, and 0.63 inches (1.6 cm) tall. The low-profile height is designed to clear most commercial door sweeps and floor thresholds.

Q: Can the BK1400-10 be cut to a shorter length in the field?

A: The non-metallic construction is compatible with field cutting using standard utility knives or miter saws. Always verify cut ends are clean and free of burrs before routing cables.

Q: What cable types fit inside the BK1400-10 channel?

A: The 3-inch-wide channel accommodates multiple low-voltage cable runs simultaneously, including Cat6 network cable, RG59 coax, and control wiring. Verify the cable bundle diameter and fill ratio against the channel cross-section before specifying for high-density runs.

Q: Is the BK1400-10 (often searched as BK1400 10) suitable for ADA-compliant installations?

A: The 0.63-inch profile height meets the low-obstacle threshold guidance relevant to most ADA floor-level obstruction requirements, but confirm with your project's ADA consultant for jurisdiction-specific compliance sign-off.

Q: Is the BK1400-10 metallic or non-metallic?

A: Non-metallic. This eliminates galvanic corrosion, prevents the raceway from acting as an unintended ground path, and produces no sharp edges when field-cut — all relevant for low-voltage signal cable installations.

The spec that drives most BK1400-10 selections is the 0.63-inch profile height — that measurement is what determines whether this raceway clears your door sweep or forces a threshold modification. On a typical commercial hollow-metal door frame, you have between 0.5 and 0.75 inches of clearance at the floor; the BK1400-10 sits right in the middle of that window, which is why it shows up so frequently in lobby camera drops and cross-corridor AV runs where the door can't be re-hung.

Technical Highlights:

• 0.63 in (1.6 cm) height: The critical spec for door-threshold clearance. Measure your actual door sweep gap before committing — if it's under 0.6 inches, you'll need a thinner profile or a threshold relief cut.
• 3 in (7.6 cm) channel width: Wide enough for a mixed low-voltage run — Cat6 + coax + control wire — without forcing cables into a tight bundle that stresses connectors at entry and exit points.
• 10 ft (3.1 m) single section: Covers a standard 10-foot room span without a mid-run coupler, which is the failure and aesthetics point most installers want to avoid on polished or finished floors.

Deployment Considerations:

• TAA compliance is confirmed for this SKU — document the BK1400-10 part number on your submittals for government or federally funded projects; the compliance is per-SKU, not blanket across the product line.
• Non-metallic means no ground path — if your installation requires a grounded raceway for EMI shielding of sensitive signal cable, this product is not the right choice; spec a metallic alternative instead.

The BK1400-10 is the right call for cross-floor low-voltage runs in finished commercial interiors — lobbies, conference rooms, and corridors — where a permanent, TAA-compliant solution needs to survive foot traffic and a facilities review without requiring floor penetration or metallic conduit.
