The RFL-AV floor boxes are perfect for applications with raised floors that require AV and power in one box.

The Q model is the larger version and accepts any two plate combinations equaling four gang. An optional 4-gang bracket is available for applications requiring a four gang plate. The D model is a small, compact unit that accepts a 2-gang plate and is supplied with a divider bracket to create 1-gang of high voltage and 1-gang of low voltage compartments. Covers and carpet trims are available in gray, black and clay. If your application requires a custom color, FSR will be happy to quote on your specific requirements.
