Buying Guide: Power And Data Floor Boxes
What to consider when choosing
Installation location and surface type matter. Concrete floors benefit from concrete-specific kits, while wood or carpeted floors may require different cutouts and finishes. Determine whether you need one box or a multi-port solution. Consider finishes that match or complement existing hardware and decors.
Power and data capacity
Check the number and type of outlets supported. Some options include RJ45, RJ11, HDMI, USB ports, and traditional 15A outlets. Keystone openings provide flexibility for future data additions.
Aesthetic and finish options
Six-color cover options exist for several Arlington models, including black, brass, nickel, and brown. Choosing a finish that harmonizes with flooring and room fixtures helps maintain a seamless look.
Concrete-specific vs. general use
Concrete floor boxes are designed to install directly into concrete floors and generally include a concrete-compatible kit. If your floor is not concrete, select a box designed for wood or carpeted applications or one with a versatile cover finish that blends into your environment.
Compatibility and expansions
Some systems require separate components (such as specific finishing plates or power/data modules) to complete the installation. Plan for future needs by selecting models with extra keystone openings or expandable port configurations.
Installation practicality
Consider whether the box requires a specific hole size (often around 5 inches) and if the installation is a retrofit or a new build. Recessed designs help maintain a clean floor surface, but require precise cutting and leveling for a flush result.
Durability and materials
Metal construction and corrosion-resistant finishes improve longevity in high-traffic spaces. For outdoor or damp locations, rust-proof materials can be crucial.
Summary tips for buyers
- Match finish with the room’s hardware and flooring.
- Confirm the number and type of ports needed today and in the future.
- Choose a recessed design to keep floors safe and flat.
