         21 . A projection screen apparatus for use with a projector configured to project an image to be watched by a viewer, the projection screen apparatus including:
 a projection screen having a viewing surface configured to display the image to the viewer;   a frame supporting the projection screen and including a plurality of frame members, the plurality of frame members including a top frame member extending along a top edge of the projection screen, the top frame member being a unitary extruded member including:
 a front wall having a first side facing the viewer and a second side opposite the first side, 
 an upper portion including a first channel extending the length of the top frame member, 
 a lower portion including a second channel extending the length of the top frame member, and 
 a plurality of ribs extending from the second side, each rib defining an undercut groove, a first rib of the plurality of ribs forming a top wall of the second channel, and a second rib of the plurality of ribs being positioned between the first channel and the second channel; and 
   at least coupler coupling the projection screen to the frame, a first coupler of the at least one coupler coupling the top edge of the projection screen to the top frame member with the top edge of the projection screen being positioned rearward of the front wall of the top frame member, the first coupler being a unitary extruded member including:
 a central body; 
 a lower circular portion extending from the central body, the lower circular portion having an open end and a channel extending the length of the first coupler, the top edge of the projection screen being located in the channel extending the length of the first coupler and the projection screen extends downward through the open end of the lower circular portion; and 
 an upper portion including a first rib and a second rib, the first rib extending from the central body in a first direction towards the first side of the front wall of the top frame member, the first rib defining with the central body an undercut groove, the second rib extending from the central body in a second direction away from the first side of the front wall of the top frame member, 
   
       wherein the first rib of the first coupler is positioned on top of a rib of the plurality of ribs of the top frame member to couple the projection screen to the top frame member, the undercut groove of the first rib of the first coupler receiving the rib of the plurality of ribs of the top frame member, the first channel of the top frame member being sized and shaped to receive the first coupler for storage of the first coupler when uncoupled from the projection screen.
