Wiremold RFB4E-OG Series Four-Compartment On-Grade Box

Introducing the Wiremold RFB4E-OG Series Four-Compartment On-Grade Box, a robust solution designed for on-grade concrete floor installations. Built to work with round 6" Evolution Series covers and compatible poke-thru systems, this box provides flexible wiring layouts and organized power distribution in commercial settings. Its four-compartment design delivers secure separation of circuits, while the tunnel compartments and adjustable routing options make it easy to adapt to changing electrical needs without sacrificing the clean floor-level look. When used with Evolution Series accessories, the RFB4E-OG delivers a professional, code-compliant floor box solution that blends seamlessly with high-traffic environments such as offices, classrooms, retail spaces, and data centers.

• Fully adjustable with tunnel compartments to tailor cable routing and space allocation precisely to your installation. The four-compartment arrangement enables safe separation of power, data, and auxiliary circuits, helping you manage heat, interference, and organization in busy environments. This flexibility supports future reconfigurations as technology and layout requirements evolve, without the need to replace the entire box. The design is optimized for on-grade concrete floors, ensuring a stable, durable foundation for floor-level connections and accessories.
• Compatibility with Evolution Series covers and poke-thru accessories for a cohesive, professional finish. The RFB4E-OG accepts round 6" Evolution Series covers for a clean, low-profile appearance that blends with surrounding flooring while enabling easy access for maintenance. It also accepts Evolution Series poke-thru covers (6CTC, 6CT, and 6CFFTC), expanding your layout options and simplifying integration with existing floor box systems. Device plates are sold separately, giving you full freedom to configure faceplates and outlets to suit your specific wiring plan.
• Designed for on-grade concrete floor installations, the RFB4E-OG provides a reliable, long-lasting solution in high-traffic areas. Its rugged construction supports rigorous commercial use, with a focus on durability and consistent performance in environments where floor boxes are subject to foot traffic, equipment movement, and routine maintenance. The box is engineered to sit flush with the floor once the chosen cover is installed, delivering a seamless look that minimizes tripping hazards and maintains accessibility for service.
• Modular, future-ready configuration supports diverse room layouts and evolving electrical needs. The four compartments can be tuned to separate circuits by function or tenant, enabling better circuit management, easier troubleshooting, and improved safety. The system also accommodates a range of devices through compatible plates (sold separately), empowering you to create a tailored installation that aligns with local codes and project specifications while preserving a tidy, professional appearance.
• Easy maintenance and serviceability for busy environments. The RFB4E-OG is engineered to simplify installation, reconfiguration, and routine servicing, reducing downtime and disruption in active spaces.

How to Install Wiremold RFB4E-OG Series Four-Compartment On-Grade Box

• Plan the layout and verify that the installation site is suitable for an on-grade concrete floor box. Check local codes and project specifications to ensure the RFB4E-OG will meet all required clearances and accessibility guidelines before starting.
• Prepare the floor opening in the concrete according to manufacturer guidelines. Accurately mark the opening size to accommodate the four-compartment box and ensure a precise fit that allows the cover to sit flush with the floor surface once installed.
• Place the RFB4E-OG into the prepared cavity, ensuring that the tunnel compartments align with your planned cable routing paths. Secure the box according to the provided mounting method to maintain stability and prevent movement under foot traffic or equipment.
• Route and organize cables through the tunnel compartments, maintaining separation between circuits as needed. Leave adequate slack for devices and future modifications, and ensure all wiring complies with applicable electrical codes and standards.
• Install device plates (sold separately) and any required outlets or data jacks in the designated compartments. Choose the appropriate Evolution Series round covers and poke-thru covers (6CTC, 6CT, 6CFFTC) to achieve the desired surface finish and accessibility. Finally, place the cover flush with the floor surface and verify smooth operation and proper alignment.
• Test the installation and functionality. Confirm that all connections are secure, that the covers seat correctly, and that any required gaskets or seals are properly engaged to resist dust, moisture, or debris ingress in accordance with project specs.
