Abstract

A storm door construction includes an internal rectangular frame providing a pane opening, the frame including left and right vertical members, a head panel and a base panel. One of the left and right vertical members comprises upper and lower vertical stile pieces and a mortise box located between the upper and lower vertical stile pieces. The mortise box has an opening sized to receive a mortise lock therein. Inside and outside skin panels shaped to cover both sides of said rectangular frame and having rectangular openings substantially in registry with said rectangular pane opening are laminated onto the frame. Both vertical members can include mortise boxes for alternate left or right side mounting of the door in an external doorframe.
