ABSTRACT:
A self-adjusting window frame unit having a corner assembly that will permit continued adjustment of the frame while providing strength for the frame at the corners and while maintaining a fully insulated frame. The unit includes right-angle corner members adapted to receive window end members having angled ends and with the corner members having projecting legs with extending side faces on opposite sides thereof to fill spaces left by notches provided in the end members. Alternatively the end members may extend into opposite legs of the corner members and the corner members may be hinged to permit relative movement of the end members to fit a window opening. With the hinged corner member the legs of the corner member are overlapping so that no air gap will develop between the legs as the legs move relative to one another.
