ABSTRACT:
A protective cover for the window sashes of awning windows is integrally formed of sheet metal and has a reversely-bent, lower marginal edge providing an inwardly-directed, shallow slot for the interhooking reception of the lower edge portion of the sash framework, and a substantially right-angular, inwardly-bent, upper marginal portion adapted to frictionally engage over the top of the window sash framework for retaining the protective cover in place. Upon full closure of the awning window, the upper portion of the covered sash framework locks behind the lower marginal portion of the next higher window sash, or the awning window frame header of the top sash, thereby securely retaining the protective cover.
