ABSTRACT:
The specification discloses an improved wood-frame glass door unit which includes a surround structure with at least two wood-frame door panels mounted within the surround structure. Each door panel includes a frame having a horizontal top rail and bottom rail maintained in a spaced relation by left and right side rails. The rails are composed of laminated wood strips which permits substantial reduction in the width of the rails and a greater glass to frame ratio. A glass pane is fitted within each frame. One door panel is fastened to the surround structure by a plurality of fasteners passing through the surround structure into the top and bottom rails and one of the side rails of the fixed panel. Angle brackets attach the opposite side rail of the fixed door panel to the surround structure. A mullion is attached to one of the side rails of the frame of the fixed door panel to add further support. The second door panel is hingedly connected to the fixed door panel adjacent the mullion such that the hingable door panel hinges against the adjacent fixed door panel.
