ABSTRACT:
A vinyl window or door screen frame which does not require clips or hooks for installation. The frame contains corner keys formed at angles greater than 91.degree. which provide a slight bow along each side of the screen frame. This feature allows the screen frame to fit snugly into the window frame. The use of vinyl makes the screen frame flexibly rigid and thus allows for the bow in the frame. The frame stays in place due to the compression force between the window frame and the bowed edges of the screen frame.
