Wiremold OFR Series Overfloor Raceway 4 Inch Poke-Thru Transition

Discover a smarter way to route power, A/V, and data through legacy poke-thru openings with the Wiremold OFR Series Overfloor Raceway 4 Inch Poke-Thru Transition. Built to replace standard 4" poke-thru fittings, this transition delivers a seamless, high-performance cable management solution that keeps spaces tidy, safe, and ready for evolving technology. Whether you’re outfitting an office, conference room, classroom, or retail environment, the OFR series provides a durable, aesthetically pleasing channel that protects cables, simplifies upgrades, and minimizes downtime. From fast installations to reliable long-term operation, this transition fits the modern workflow where clean connectivity and flexible layouts matter most.

With the OFR Series, you’re choosing more than a pass-through. You’re selecting a purpose-built cable manager designed to handle multi-media demands, including power, data, and high-bandwidth A/V. Its overfloor design reduces clutter by consolidating cables into a single, protected path, while its transition feature offers a smooth, professional finish at the poke-thru opening. This means less maintenance, fewer trips, and more efficient space utilization as your environment evolves—perfect for spaces that frequently reconfigure, reassign rooms, or upgrade technology.

The OFR 4-inch poke-thru transition excels at delivering reliable connectivity in busy environments. Its durable construction stands up to heavy use and foot traffic without compromising performance, while the clean white finish blends with most interior palettes. The design emphasizes safety and organization: cables are shielded from dirt and wear, accessibility remains straightforward for technicians, and the system supports a broad range of cables and connectors. By consolidating power, A/V, and data in one streamlined pathway, you can reduce the need for multiple wall penetrations and minimize disruption during upgrades or redeployments.

In addition to practical benefits, the OFR Series supports scalable installations. As your digital ecosystem expands, you can route additional cables through the same 4" opening without sacrificing ease of maintenance. The transition fitting is engineered to integrate with existing poke-thru openings, enabling quick retrofits in spaces with outdated infrastructure. This makes it an ideal upgrade for historical or retrofitted buildings where modernization must happen without major renovations. By combining durable materials, thoughtful engineering, and a user-friendly interface, the OFR Series sets a new standard for in-floor cable management and poke-thru transitions.

From a consumer perspective, the OFR Series translates into real-world advantages: simpler cable management reduces wear and tear on wires, safer floors due to reduced loose cabling, and a professional look that enhances client or stakeholder perception. The solution is designed to be accessible for technicians while staying resilient under daily use. It supports a wide range of cable types, including power cables and data/AV runs, and is suitable for commercial, educational, and commercial interiors where quick reconfiguration and dependable performance are essential. In short, the OFR 4" poke-thru transition is the practical, long-term answer to in-floor cable routing that keeps up with the pace of modern technology and the demands of active workspaces.

How to install Wiremold OFR Series Overfloor Raceway 4 Inch Poke-Thru Transition

• Step 1 — Prepare the area: Before installation, power down relevant circuits and verify that the 4" poke-thru opening is clean and free of debris. Measure the opening to confirm compatibility with the OFR transition and remove any old cover plates or obstructions. Clear the surrounding floor space to provide a stable working area for mounting hardware.
• Step 2 — Plan cable routing: Map the intended cable routes, listing the number and type of cables (power, audio/visual, data) destined for the channel. Plan for future growth by leaving a little extra capacity and ensuring there are no kinks or sharp bends in the planned path. Identify entry and exit points from the poke-thru opening and align the transition base accordingly.
• Step 3 — Install the transition base: Position the OFR transition base over the 4" opening, ensuring the alignment with the opening's edges. Secure the base using the included mounting hardware according to the manufacturer’s guidelines. If required by your floor type, use additional fasteners or adhesive as specified to ensure a secure, level fit and to prevent movement over time.
• Step 4 — Route cables and connect: Gently feed power, A/V, and data cables into the channel, avoiding over-tight bends. Label cables for easy future identification. If you anticipate updates or reconfigurations, consider leaving extra slack within the channel and using cable management accessories to organize and separate cable groups for easier maintenance.
• Step 5 — Attach the cover and test: Snap the cover into place to seal the channel and provide a clean, finished appearance. Confirm that the cover sits flush with the floor surface and that there is no gap around the poke-thru opening. Restore power and test each connected device to ensure proper operation and signal integrity across power, data, and A/V lines. Finally, tidy any loose cables and verify that the installation maintains a safe, tripping-resistant floor.
