Abstract: Molding, which is attached directly to the outside of a house around a window, includes a continuous groove for receiving the edges of a sheet of flexible screening. A strip of flexible tubular rubber is used to force the screen into the groove and operates to frictionally retain the screen in engagement with the molding, and a decorative cap can then be snap fitted into the groove to further hold the screen in place. A flexible retaining strip may be removably attached to the decorative cap and can include a plurality of barbed tacks which engage the tubular rubber holding ring. The barbed tacks operate to remove the tubular rubber member when the decorative cap is pulled away from the molding so as to facilitate an easy removal of the screen for purposes of replacement or repair.
