Middle Atlantic Over Floor Raceway Base - OFRB-8

Middle Atlantic OFRB-8 Over Floor Raceway Base

Overview

The Middle Atlantic OFRB-8 is an 8-inch over floor raceway base designed to route and protect cabling runs across floor surfaces in commercial, government, and institutional environments. As part of the Middle Atlantic raceway and cable management line, the OFRB-8 provides a low-profile pathway for power, data, and AV cables in spaces where in-floor conduit isn't feasible — think open office retrofits, conference room buildouts, and security infrastructure deployments where cables must cross walkways without creating trip hazards or violating code.

The OFRB-8 (often searched as OFRB 8) ships as a single 96.5-inch section — just over 8 feet — giving installers a full-length base piece that minimizes seams in longer runs. At 8 inches wide, it accommodates multi-conductor bundles including combined power and low-voltage cable runs common in access control and surveillance infrastructure projects.

Key Features

• TAA Compliance: The OFRB-8 carries TAA (Trade Agreements Act) compliance, making it eligible for federal government procurement, GSA schedules, and projects requiring domestic/qualifying-country sourcing. If your project has Buy American or TAA requirements, this matters at the specification stage — not as an afterthought.
• 8-Inch Channel Width: The wider 8-inch profile handles high-density cable bundles — multiple Cat6 runs alongside low-voltage security cabling — without forcing tight bend radii that can degrade signal integrity in structured cabling installations.
• Full 8-Foot Section Length: At 96.5 inches per piece, fewer seams means a cleaner installation and fewer potential snag points along the raceway run. On a 20-foot hallway crossing, you're looking at two pieces plus a short cut rather than four or five shorter sections.
• Over-Floor Design: Intended for surface-mount floor routing where trenching or in-floor conduit isn't practical. This is the right solution for retrofit deployments in occupied buildings, historic structures, or any site where floor penetration is restricted.

Integration & Compatibility

The OFRB-8 is the base component of Middle Atlantic's OFR Series over floor raceway system. It is designed to pair with matching OFR Series cover pieces, end caps, couplers, and transition ramps from the same product family — source covers and accessories from the same OFR line to ensure dimensional fit. For cable management planning in security and AV deployments, verify the total cable fill against the 8-inch channel width before specifying; Middle Atlantic publishes fill calculators for the OFR series. This product is compatible with standard structured cabling infrastructure deployments and integrates with any brand-agnostic cabling system where physical protection is the requirement.

Frequently Asked Questions

Q: Is the Middle Atlantic OFRB-8 TAA compliant?

A: Yes. The OFRB-8 is TAA (Trade Agreements Act) compliant, making it eligible for federal, state, and government projects with TAA or Buy American sourcing requirements.

Q: What is the length of a single OFRB-8 section?

A: Each OFRB-8 section ships at 96.5 inches (just over 8 feet) in length, based on the verified shipping dimensions.

Q: What cable types can the OFRB-8 accommodate?

A: The 8-inch channel width is designed to handle multi-conductor bundles including combined power and low-voltage cable runs. Specific fill capacity should be verified against Middle Atlantic's OFR series fill guidelines for your cable mix.

Q: Does the OFRB-8 come with a cover?

A: The OFRB-8 is the base component only. Matching covers, end caps, and transition ramps are separate OFR Series accessories and must be ordered independently.

Q: Is the OFRB-8 suitable for outdoor use?

A: The available evidence does not confirm an outdoor or environmental rating for the OFRB-8. Middle Atlantic's OFR Series is designed for commercial interior applications; verify with the manufacturer before specifying for outdoor or high-moisture environments.

James Everett

The OFRB-8 is a straightforward specification call in the right context: you need a TAA-compliant, 8-inch over-floor raceway base for a government or institutional project where floor penetration isn't on the table. The 96.5-inch section length is the detail that actually affects installation planning — longer sections mean fewer joints on a corridor run, and fewer joints mean a cleaner, more maintainable pathway for the cable infrastructure underneath.

Technical Highlights:

• TAA Compliance: Verified for this SKU — covers federal procurement requirements without a waiver request or substitution process mid-project.
• 96.5-Inch Section Length: At just over 8 feet per piece, a standard 24-foot hallway crossing requires only three sections, minimizing seam count and reducing the number of couplers needed in the bill of materials.
• 8-Inch Channel Width: Wider than entry-level raceway options, this accommodates bundled security cabling — e.g., combined Cat6, 18/2 power, and coax — in a single pass without compression damage to cable jackets.

Deployment Considerations:

• The OFRB-8 is the base only — budget for matching OFR Series covers, end caps, and transition ramps separately. Omitting transition ramps on high-traffic crossings is a common oversight that creates a trip liability at the raceway edge.
• TAA compliance is confirmed for this SKU; if your project spec also requires NDAA Section 889 compliance on electronic components, that applies to the active devices being cabled — not to this passive raceway base — but document it in your submittal set regardless.

This is the right base piece for a GSA or government facility retrofit where you're routing security and AV cabling across occupied floor space and need the TAA paper trail to close out the procurement without exceptions.
