Leviton 2-Gang Concrete Floor Box System
The Leviton FBBOX-GY framework supports a two-gang installation within concrete floors, designed to pair with the FBLEV-GY reducer kit and a Leviton finished floor plate sold separately. Its 6.25″ height accommodates multiple modules for power and data needs. This system emphasizes modularity and robust integration with Leviton accessories, making it suitable for modern workspaces and renovation projects requiring a clean, integrated appearance.
Key considerations include compatibility with power and data conduits, the necessity to source the matching floor plate, and ensuring the extended depth matches the floor structure. Installation should attend to proper sealing and cable routing to maintain floor integrity and safety in concrete pours.
Non-Metallic Floor Box For Concrete Pour
This rigid PVC non-corrosive floor box is designed for concrete pours with a 3-inch minimum pour depth and a substantial 117 cubic inches of capacity. Its non-metallic construction reduces conduction concerns and simplifies installation in new concrete slabs, making it a practical choice for high-traffic areas requiring durable, cavity-rich outlets.
Considerations include the pour depth requirements, compatibility with a range of receptacles, and long-term performance in concrete environments. The box is well-suited for industrial or commercial installations where corrosion resistance and large capacity matter most.
ARLINGTON FLBC4580 Recessed Floor Box
ARLINGTON’s recessed model is designed for concrete floors and fits most 4.5″ inside diameter round PVC floor boxes. It offers a brass or nickel finish option and includes a 15 amp Decora style power outlet. The kit-oriented approach emphasizes a streamlined install and a focus on a tidy, reusable receptacle solution in concrete structures.
Important considerations include finish choice, compatibility with existing round PVC boxes, and ensuring the recessed design aligns with furniture layout to avoid protrusions that could create trip hazards.
ARLINGTON FLBC4500 Concrete Floor Box
ARLINGTON’s FLBC4500 offers a low-profile concrete floor box solution with a mud cover option. Built for new concrete installations, it emphasizes an unobtrusive footprint while providing reliable receptacle access. The mud cover helps protect the receptacle area when not in use and can adapt to various interior layouts.
Key considerations include the availability of the mud cover accessory, the installation depth, and how the low-profile profile affects furniture placement and cable routing in the surrounding area.
Creemrib Recessed Floor Outlet Kit
The Creemrib kit provides a recessed two-gang floor outlet with a durable aluminum housing and a double-door cover plate. It includes a 15A duplex receptacle and three USB charging ports, combining traditional power with USB-enabled charging in a single floor installation. The integrated cover design reduces visible outlets when not in use, preserving floor aesthetics in commercial or modern home spaces.
Considerations include the overall depth (2.17 inches) and compatibility with various floor types, as well as the potential for USB ports to become a daily-use consideration for high-traffic areas. The kit is positioned for both industrial and office environments seeking functional, accessible power with modern charging options.
Buying Guide: Key Purchase Considerations For Concrete Floor Boxes
When choosing a concrete floor box, consider your application, future needs, and the installation environment. The following points help compare options objectively:
- Installation depth and footprint: Ensure the box fits within the concrete pour depth and does not interfere with structural elements or furniture placement.
- Electrical capacity and module options: Match the outlet types (duplex, Decora, USB ports) to expected use and load requirements. Plan for power, data, and media needs if required.
- Material and durability: Concrete installations benefit from corrosion-resistant materials. PVC or aluminum housings balance durability with ease of installation.
- Finish and aesthetics: recessed or low-profile kits reduce tripping hazards and maintain a clean floor look, especially in commercial spaces.
- Access and maintenance: Choose designs with easy cover access or automatic closing flaps to reduce debris intrusion and wear over time.
- Compatibility with accessories: Verify required floor plates, mud covers, leveling rings, and reducers are readily available for the chosen system.
- Code compliance and safety: Ensure the product adheres to local electrical codes and proper sealing to prevent moisture ingress in concrete installations.
- Future-proofing: Consider models that support USB charging or data outlets, enabling smoother upgrades as needs evolve.
In choosing a concrete floor box, balance upfront install effort with long-term reliability and ease of use. For environments prioritizing modular upgrade paths, brands offering compatible accessory ecosystems can reduce total cost of ownership over time. For renovation projects, recessed and low-profile designs often minimize disruption while preserving floor aesthetics. For new construction, robust PVC or metal housings paired with appropriate seals ensure durability against routine floor traffic and equipment movement.
