Arlington FLBC4580 Recessed Power & Data Round Floor Box for 4.5-Inch Concrete Boxes (Brass)

Arlington FLBC4580: Recessed Power and Data Round Floor Box for Concrete Floors

The Arlington FLBC4580 is a recessed power and data round floor box designed to fit inside most concrete floor boxes with a 4.5-inch inside diameter. It is intended for concrete installations and is not compatible with standard wood floors. This solution brings power and data access to floors while remaining discreet and stylish, making it a practical choice for spaces that prioritize a clean, seamless look.

Built for flush-to-floor installation, the unit features an ultra-thin stamped steel flange paired with a zinc die-cast cover. When installed, outlets sit level with the surrounding surface, reducing trip hazards and preserving a smooth walking surface. The design also enables power and low-voltage connections to share a single box, helping to minimize clutter and simplify coordination during installation.

While results can vary by project, this floor box provides a robust, purpose-built solution for concrete installations that require integrated power and data access in a single, durable box.
