Example vent cover assemblies may include a support plate configured to be secured over a duct, and a flush mount vent cover. The support plate may define a plurality of first airflow apertures configured to permit airflow from the duct through the support plate. The vent cover may define a second plurality of airflow apertures that are 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. The vent cover may obstruct the first airflow apertures when the vent cover is in a second installed position overlying the support plate. ## Claims ### Claim 1 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; 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 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. ### Claim 2 (depends on 1) The floor vent cover assembly of claim 1, wherein the second plurality of airflow apertures are positioned asymmetrically with respect to a vent cover outermost perimeter defined by the vent cover. ### Claim 3 (depends on 1) The floor vent cover assembly of claim 1, 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. ### Claim 4 (depends on 1) The floor vent cover assembly of claim 1, further comprising a flooring defining the adjacent floor surface. ### Claim 5 (depends on 4) The floor vent cover assembly of claim 4, wherein the vent cover upper surface and adjacent floor surface are each formed of a same material. ### Claim 6 (depends on 1) The floor vent cover assembly of claim 1, wherein the vent cover includes a magnetic backing, and the support plate is formed of a magnetically susceptible material. ### Claim 7 (depends on 6) The floor vent cover assembly of claim 6, wherein the magnetically susceptible material is a metallic material. ### Claim 8 (depends on 1) The floor vent cover assembly of claim 1, wherein the vent cover is placed into direct contact with the support plate in the first and second installed positions. ### Claim 9 (depends on 1) The floor vent cover assembly of claim 1, wherein the support plate defines a support plate outermost perimeter configured to be installed to an underside of a floating floor defining the adjacent floor surface, and the vent cover defines a vent cover outermost perimeter disposed within the support plate outer perimeter. ### Claim 10 (depends on 1) The floor vent cover assembly of claim 1, further comprising a support plate outer frame surrounding at least a portion of the support plate and configured to be secured to a subfloor, wherein the support plate is selectively removable from the support plate outer frame when the support plate outer frame is secured to the subfloor. ### Claim 11 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. ### Claim 12 (depends on 11) The floor vent cover assembly of claim 11, wherein the support plate defines a support plate outermost perimeter configured to be installed to an underside of a floating floor defining the adjacent floor surface, and the vent cover defines a vent cover outermost perimeter disposed within the support plate outer perimeter. ### Claim 13 (depends on 11) The floor vent cover assembly of claim 11, further comprising a support plate frame surrounding at least a portion of the support plate and configured to be secured to a subfloor, wherein the support plate is selectively removable from the support plate frame when the support plate frame is secured to a subfloor. ### Claim 14 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. ### Claim 15 (depends on 14) The method of claim 14, wherein the second plurality of airflow apertures are positioned asymmetrically with respect to a vent cover outermost perimeter defined by the vent cover, and 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. ### Claim 16 (depends on 14) The method of claim 14, wherein the support plate defines a support plate outermost perimeter configured to be installed to an underside of a floating floor defining the adjacent floor surface, and the vent cover defines a vent cover outermost perimeter disposed within the support plate outer perimeter. ### Claim 17 (depends on 14) The method of claim 14, further comprising surrounding at least a portion of the support plate with a support plate outer frame, the support plate outer frame configured to be secured to a subfloor, wherein the support plate is selectively removable from the support plate outer frame when the support plate outer frame is secured to the subfloor. ### Claim 18 (depends on 14) The method of claim 14, further comprising establishing the vent cover being formed of a same material as a surrounding flooring defining at least in part the vent aperture. ### Claim 19 (depends on 18) The method of claim 18, further comprising forming the vent aperture in the flooring. ### Claim 20 (depends on 14) The method of claim 14, further comprising aligning the upper surface of the vent cover such that it extends substantially continuous with the adjacent floor surface when installed overlying the support plate.
