Because air does not come out of the duct work, dampers are non included (because there is no forced air flow to control). Floor return air grilles will however accept a small drib in area that volition become into your floor opening, just there volition not be a damper. At that place is not a wide selection of styles and finishes for floor grilles, and if yous have a small enough opening (that matches flooring register sizes) yous could use a decorative flooring register and leave the damper completely open. Other common names for flooring air return grilles: floor grilles, flooring returns, floor grates, etc.
