The Lew Electric RCFB-2-DB allows you to plug into your floor box and not have the plugs visible creating a low profile look. The box allows you to hide your plug ends in the box by plugging in your cord ends low in the box, and not at the surface. This creates a more flush look and eliminates tripping hazards. Rubber grommets are included to protect the cords around the hole in the dark bronze cover when they are in use.
