an upper air dam having an arcuate first central portion comprising a leading edge and a trailing edge, the arcuate central portion comprising an outer surface; a lower air dam having an arcuate second central portion a leading edge and a trailing edge, the arcuate second central portion comprising an outer surface; an upper air deflector comprising a first forward lip, a first rear edge and a bottom surface positioned immediately adjacent and in contact with the arcuate first central portion of the upper air dam; a lower air deflector comprising a second forward lip, a second rear edge and a top surface positioned immediately adjacent and in contact with the second central portion of the lower air dam; an air flow control mechanism operatively connected to the upper air dam or the lower air dam to rotate both the upper air dam and the lower air dam simultaneously; and, wherein the upper air dam and the lower air dam rotate in opposite directions upon operation of the air flow control mechanism from an open position to a closed position in which the first trailing edge and the second trailing edge are in direct contact with each other or overlap each other; and in which the first forward lip overlaps with the first rear edge and the second forward lip overlaps with the second rear edge. ### Claim 2 (depends on 1) The air register of claim 1 wherein the upper air dam and the lower air dam each further comprise a rounded portion at each end. ### Claim 3 (depends on 2) The air register of claim 2 wherein each of the rounded portions further comprises a plurality of teeth. ### Claim 4 (depends on 3) The air register of claim 3 wherein the plurality of teeth engage each other to provide the rotation of the upper air dam and the lower air dam. ### Claim 5 (depends on 1) The air register of claim 1 wherein the upper air dam and the lower air dam rotate towards each other to restrict air flow through the at least one opening. ### Claim 6 (depends on 1) The air register of claim 1 wherein air does not flow through the at least one opening when the upper air dam trailing edge and lower air dam trailing edge are in contact with each other. ### Claim 7 (depends on 1) The air register of claim 1 wherein the upper air dam rotates within the upper air deflector and the lower air dam rotates within the lower air deflector. ### Claim 8 (depends on 1) The air register of claim 1 wherein the upper air dam further comprises a pin aperture. ### Claim 9 (depends on 8) The air register of claim 8 wherein the air flow control mechanism further comprises a pin. ### Claim 10 (depends on 9) The air register of claim 9 wherein the pin extends through the pin aperture and causes rotation of the upper air dam upon rotation of the air flow control mechanism. ### Claim 11 (depends on 1) The air register of claim 1 wherein the upper air deflector and the lower air deflector contact a duct upon installing the air register. ### Claim 12 (depends on 1) The air register of claim 1 wherein the upper air dam, the upper air deflector, the lower air dam, and the lower air deflector together prevent air flow through the at least one opening when the trailing edge of the upper air dam contacts the trailing edge of the lower air dam. ### Claim 13 (depends on 1) The air register of claim 1 wherein there are no more air dams than the upper air dam and the lower air dam. ### Claim 14 (depends on 13) The air register of claim 13 wherein all of the air passing through the air register only passes between the upper air dam and the lower air dam. ### Claim 15 (depends on 1) The air register of claim 1 further comprising a perimeter gasket. ### Claim 16 (depends on 1) The air register of claim 1 further comprising an end cap on opposing sides of the upper air dam and the lower air dam. ### Claim 17 (depends on 16) The air register of claim 16 wherein the upper air dam and the lower air dam are each connected to each end cap. ### Claim 18 (depends on 1) The air register of claim 1 wherein the air flow control mechanism extends forward of the front surface. ### Claim 19 (depends on 1) The air register of claim 1 further comprising a plurality of vertical vanes and wherein the upper air dam and the lower air dam are oriented horizontal. ### Claim 20 (depends on 1) The air register of claim 1 wherein the bottom surface of the upper air deflector has an arcuate bottom surface complementary to the arcuate first central portion and the top surface of the lower air deflector has an arcuate top surface complementary to the arcuate second central portion.
