Middle Atlantic OFR Base AND Cover - OFRBC-8R

Middle Atlantic OFRBC-8R Over-Floor Raceway Base and Cover

Overview

The Middle Atlantic OFRBC-8R is an 8-foot over-floor raceway base and cover kit designed to route and protect low-voltage cabling across open floor surfaces — the kind of clean, trip-hazard-free cable management that inspectors and facility managers actually want to see. At 6.88 inches wide and just 0.63 inches in profile height, it sits low enough to clear most threshold transitions while providing enough internal width to bundle multiple cable runs in a single pass. If you are running power, data, or AV cabling across a conference room, lobby, or open office floor without the option to trench or drop through a raised floor, the OFRBC-8R is the format to reach for.

TAA compliance is confirmed for the OFRBC-8R (often searched as OFRBC 8R), making it a straightforward fit for GSA schedules, federal contracts, and state procurement programs that require Trade Agreements Act conformance. This is worth confirming at the bill-of-materials stage for any government or education project — it eliminates a common sourcing substitution problem later in the project cycle.

Middle Atlantic is part of the Middle Atlantic product line, a brand with a long history in AV and security rack infrastructure. The OFRBC series sits within their broader cable management lineup, designed to work alongside their raceway accessories and transition pieces.

Key Features

• 8-Foot Run Length: Each OFRBC-8R section covers 2.4 meters end-to-end. For a 24-foot crossing — a common conference room or lobby span — you need three sections, which keeps your cut-list simple and your connector count low. Fewer joints means fewer potential catch points and a cleaner finished appearance.
• 6.88-Inch Interior Width: At 17.5 cm wide, this raceway accommodates multiple cable runs side by side — HDMI, Cat6, and a pair of low-voltage power leads can coexist without bundling them into a single compressed stack. That separation matters for minimizing crosstalk on longer AV runs and for future-proofing the pathway when you need to pull additional cables.
• 0.63-Inch Floor Profile: The 1.6 cm height is low enough to comply with most ADA ramp-transition requirements when used with compatible end ramps, and low enough that rolling equipment (carts, presentation stands, service equipment) can cross it without catching. Confirm local ADA and OSHA requirements for your specific installation — this profile is designed with pedestrian traffic in mind, not as a substitute for proper transition accessory selection.
• TAA Compliant: Confirmed TAA compliance means this product qualifies for GSA Schedule purchases and federal/state government contracts without requiring a waiver. For integrators bidding on government facilities, courthouses, or public education buildings, this eliminates a sourcing risk that can hold up project close-out.
• Base and Cover Included: The OFRBC-8R ships as a matched base-and-cover unit rather than requiring separate part numbers for each component. That simplifies procurement — one line item covers both the tray and the lid for each 8-foot section.
• Compact Shipping Profile: Shipping dimensions of 96 inches x 8 inches x 2 inches mean these pack flat and stack efficiently in a cargo van or on a pallet. For multi-room or multi-floor deployments where you are staging material across a job site, the low bulk-per-section is a practical advantage.

Integration and Compatibility

The OFRBC-8R is designed as part of the Middle Atlantic OFR Series over-floor raceway system. For complete runs, pair it with compatible cable management accessories from the same series — end caps, inside and outside corner pieces, T-connectors, and reducer ramps — to handle direction changes and threshold transitions without field-fabricating cuts. Verify fitting compatibility within the OFR Series before ordering; mixing series can produce gaps at joints that defeat the cable protection and finished-appearance goals of the installation.

This raceway is suited for low-voltage and data cabling in commercial interiors: security camera power and data drops, access control wiring, AV distribution in conference and training rooms, and structured structured cabling pathways in open-plan spaces. It is not rated for high-voltage power wiring — consult local electrical codes and the NEC for branch-circuit wiring requirements in floor raceways.

Frequently Asked Questions

Q: Is the Middle Atlantic OFRBC-8R TAA compliant?

A: Yes. The OFRBC-8R is confirmed TAA (Trade Agreements Act) compliant, making it eligible for GSA Schedule and federal/state government procurement without a sourcing waiver.

Q: What are the internal dimensions of the OFRBC-8R raceway?

A: The OFRBC-8R is 6.88 inches (17.5 cm) wide and 0.63 inches (1.6 cm) in depth/height, with each section covering 8 feet (2.4 meters) in length.

Q: Does the OFRBC-8R include both the base and the cover?

A: Yes. The OFRBC-8R is a base-and-cover kit — both components are included under this single part number, so you do not need to order them separately.

Q: How many sections do I need to cross a 24-foot span?

A: Three OFRBC-8R sections cover exactly 24 feet (7.2 meters). Plan for additional transition and corner accessories if the run involves direction changes or threshold crossings.

Q: Is the OFRBC-8R suitable for high-voltage electrical wiring?

A: No. This raceway is designed for low-voltage and data cabling. Consult local electrical codes and the NEC before routing any branch-circuit or line-voltage wiring in a floor raceway.

Q: What accessories are compatible with the OFRBC-8R?

A: The OFRBC-8R is part of the Middle Atlantic OFR Series. Compatible accessories include end caps, inside/outside corner pieces, T-connectors, and reducer ramps within the same OFR Series. Verify series compatibility before ordering to ensure proper joint fit.

The Middle Atlantic OFRBC-8R comes up on commercial integration projects whenever you are bridging an open floor run — conference rooms, lobbies, or training spaces — and a conduit trench or raised-floor path is not on the table. The 6.88-inch width is the spec that actually drives the decision here: it is wide enough to run security camera cabling, access control wiring, and AV data in parallel without forcing everything into a single compressed bundle, which matters for maintaining signal integrity on longer Cat6 runs and for leaving room to pull additional cables when the room layout changes.

Technical Highlights:

• 8 ft (2.4 m) section length: Longer sections mean fewer joints per run — on a 24-foot lobby crossing, three sections and two joints versus more with shorter-format raceways. Fewer joints reduce trip-hazard risk at seams and cut installation time.
• 0.63 in (1.6 cm) floor profile: This low profile is intentional for pedestrian-traffic zones. It pairs with reducer ramp accessories to meet transition requirements for rolling equipment and ADA-conscious designs — but select the correct ramp part from the OFR Series; the base alone does not handle that transition.
• TAA Compliant: Confirmed for this part number. For any project touching a GSA schedule, federal agency, or state procurement contract, TAA compliance on every bill-of-materials line item is a close-out requirement — confirmed here, no waiver needed.

Deployment Considerations:

• Plan your accessory order at the same time as the OFRBC-8R sections. Corner pieces, T-connectors, and end caps are separate SKUs within the OFR Series — a missing inside corner piece will stall the installation on a multi-directional run.
• The 0.63-inch profile is not a universal ADA compliance guarantee. Reducer ramp accessories and local AHJ interpretation determine whether a specific installation meets applicable accessibility standards — verify before final close-out on public-access spaces.

The OFRBC-8R is the right specification for commercial AV and low-voltage security integrators running cable across open floors in government, education, or corporate facilities where TAA sourcing is a contract requirement and a clean, low-profile finish is non-negotiable.
