RACO 6239BP Brass Floor Kit
The RACO 6239BP Brass Floor Kit combines a recessed duplex 15A tamper-resistant device with an adjustable steel box finished in brass. It provides a safe, concealed receptacle ideal for spaces with children or high traffic. The design supports power or data use with back and side knockouts for wiring access, enabling flexible cable, USB, Ethernet, or cord connections. It helps to prevent plug protrusion and surface clutter, contributing to a clean floor appearance. Removable neoprene gaskets allow independent use of either side of the receptacle with the cover closed, promoting neat wiring and easy maintenance.
RACO 6239BK Black Floor Kit
The 6239BK version mirrors the brass model in function but offers a black finish for a modern, low-profile look. It includes a recessed duplex 15A TR device and an adjustable steel box, with a 5A, 125V receptacle that conceals the plug for child safety and a clean floor surface. Its intelligent design features back and side knockouts for convenient wiring access, suitable for various data and power needs. Pre-assembled flange and cover reduce installation time, while neoprene gaskets enable flexible use of either receptacle side with the cover closed.
ARLINGTON FLBRF101BL-1 Retrofit
The Arlington FLBRF101BL-1 retrofit electrical floor box provides a 20.0 cubic inch box designed for flush-to-floor installation in existing floors. It includes a NM94 connector, a duplex receptacle, back plate, gasketed cover, and screws, facilitating a quick upgrade to floor power and data access. The retrofitting approach helps preserve floor aesthetics while delivering reliable low-profile power distribution, especially in spaces where removing and replacing entire floor boxes is impractical.
RACO 6239NI Nickel Floor Kit
The nickel-finished version of the recessed duplex 15A TR device provides a durable, tamper-resistant solution with similar wiring flexibility as the brass and black variants. Its nickel finish complements contemporary interiors while maintaining the same advantages: concealed plugs, back and side knockouts for easy wiring, and removable neoprene gaskets for independent receptacle use with the cover closed. It is designed to fit flush within the floor, reducing protrusion and maintaining a tidy floor surface.
Access Floor Systems In-floor Box
This large in-floor box from Access Floor Systems includes plates for two standard duplex outlets, two double RJ45 plates, and a gasketed cover with a carpet depression. The steel box is optimized for computer-room raised floors or other commercial settings where multiple outlets and data ports are required from a single floor location. Note that it is not UL-listed for general use in non-computer environments, and its design prioritizes access and modularity in raised floor systems.
Buying Guide: Key Purchase Considerations
When selecting an in-floor electrical box, consider size, finish, and compatibility with your floor type. Finishes like brass, black, and nickel can coordinate with fixtures and furniture, while a low-profile design minimizes trip hazards. Look for recessed, tamper-resistant receptacles for enhanced safety, especially in homes with children or high-traffic areas. Wiring access is important; models with back and side knockouts provide flexibility for power, data, USB, or Ethernet connections. Installation ease matters: pre-assembled flanges, fast-install features, and gasketed covers help achieve a clean, professional look. For retrofit projects, check that the unit supports flush installation and includes necessary connectors and screws. Finally, evaluate whether you need a single-gang unit for a compact setup or a larger floor box with multiple outlets and data plates for high-demand spaces.
Safety and durability are central considerations. Tamper-resistant outlets reduce accidental contact, while durable finishes like brass, nickel, or powder-coated black resist wear in busy environments. Ensure compatibility with your flooring material—whether carpet, tile, wood, or concrete—and note whether the box is rated for raised floors or retrofit installations. If you require data and network access in addition to power, verify that knockouts accommodate Ethernet and USB cables or that the design supports modular expansion. Price should reflect long-term value, given the complexity of installation and the potential need for professional wiring.
In summary, the right in-floor electrical box blends safety, accessibility, and aesthetics. Whether you need a stylish brass finish for a foyer, a black low-profile option for modern interiors, or a large, data-ready floor box for an office, the options above provide reliable choices across finishes and configurations.
