A window framing system (1) adapted to incorporate an integral framed screen device (2). The system includes window frame components that define a screened opening (4), wherein at least two opposed sides of the frame components each include recessed retaining channels (7) and (8) that face into the opening and which are adapted to receive therein a portion of the frame of the screen device (2). The channels are respectively sized and spaced to facilitate loading of the screen into the channels by rotation and translation with an excess clearing within at least one of the channels, while enabling the screen to fully cover the opening when repositioned in an installed position in which the frame of the screen also extends into the other of said opposed channels. The system also includes means to captively retain the assembled screen in the installed position. In the preferred form of the invention adapted to incorporate an integral security screen device, the retaining means includes a retractable pin mechanism (11) that prevents translation of the screen within the channels thereby preventing its removal.
