Abstract
Abstract A screen assembly comprises a hollow or semi-hollow frame with interconnected side and end sections. Each section has a hollow channel portion terminating in a continuous screen ledge intermediate its opposite sides providing a peripheral support. A series of longitudinally spaced projections extend from said ledge adapted to retainingly engage and extend through peripheral portions of a screen spanning said frame and bearing upon said screen ledge. A removable apertured strip overlies said screen and said screen ledge retainingly engaging said projections and screen. A continuous glass support ledge is laterally displaced and extends from the screen ledge, and is adapted to alternately support a glass defining a storm window; said strip overlying and retainingly engaging said glass.
