Floor vent assembly

A floor vent cover assembly, comprising:

• a support plate configured to be secured over a duct, the support plate defining a plurality of first airflow apertures configured to permit airflow from the duct through the support plate, the support plate defining a support plate outermost perimeter;
• and
• a flush mount vent cover having an upper surface configured to extend substantially continuous with an adjacent floor surface when installed overlying the support plate, the vent cover defining a second plurality of airflow apertures, the second plurality of airflow apertures positioned asymmetrically with respect to a vent cover outermost perimeter defined by the vent cover, the second plurality of airflow apertures positioned in the vent cover such that the second plurality of airflow apertures are aligned with the first airflow apertures when the vent cover is in a first installed position directly contacting and overlying the support plate, and the vent cover obstructs the first airflow apertures when the vent cover is in a second installed position directly contacting and overlying the support plate, wherein the vent cover is configured to be placed into the second installed position from the first installed position by rotating the vent cover 180 degrees.

A method of installing a floor vent cover assembly, comprising:

• positioning a support plate adjacent a vent aperture defined by a flooring, the support plate defining a plurality of first airflow apertures configured to permit airflow from a duct through the support plate;
• and
• overlying the support plate with a flush mount vent cover having an upper surface configured to extend substantially continuous with an adjacent floor surface when installed overlying the support plate, the vent cover defining a second plurality of airflow apertures, the second plurality of airflow apertures positioned in the vent cover such that the second plurality of airflow apertures are aligned with the first airflow apertures when the vent cover is in a first installed position overlying the support plate, and the vent cover obstructs the first airflow apertures when the vent cover is in a second installed position overlying the support plate.
