Claim 15:
16. A method for fitting a retractable screen system to a fenestration assembly, the fenestration assembly including a sash and a frame surrounding the sash, the method comprising:
coupling a pair of edge rails to outer surfaces of jambs on opposing sides of the frame, each of the edge rails forming a rail slot;
coupling a screen assembly to an outer surface of a sill or a head of the frame such that a control bar of the screen assembly projects into each of the rail slots, the screen assembly including a roller assembly disposed within a roller housing and screen material coupled to the roller assembly and to the control bar;
coupling a catch assembly to an outer surface of a lower rail or an upper rail, respectively, of the sash such that a catch element of the catch assembly automatically engages a hook element of the control bar and the screen material unwinds from the roller assembly as the sash slides away from the roller assembly and winds around the roller assembly as the sash slides toward the roller assembly; and
rotating the catch assembly away from the control bar of the screen assembly when the sash is rotated out-of-plane resulting in release of the screen assembly from the sash, wherein the hook element automatically disengages from the catch element as the sash is tilted out of a plane formed by the frame.
