Abstract
A frame assembly for an air distribution system includes a damper assembly, a louver assembly, and a screen frame. Air flows through the damper assembly and the louver assembly, where the damper assembly terminates in a first flange and the louver terminates in a second flange. The first flange and the second flange are coupled to one another about a screen frame such that the screen frame is captured by abutting the first flange and the second flange.
