ABSTRACT:
A sliding door is constructed with a rectangular metal framework of C-frame channel rail sections joined at their corners. A plurality of vertically spaced horizontal reinforcing struts join the frame side rails. The top rail of the door is slidingly hung from a track by hangers including hanger brackets. The bottom frame rail is held in position by a guide track. A thin siding panel and other structure is secured to the front flanges of the framework. Twisting of the top rail, caused by the forwardly offset weight of the front mounted structure including the siding panel, is prevented by braces connected between the top rail rear flange immediately adjacent the hanger brackets and the rear flange of the next lowermost horizontal strut. Wind-caused twisting of the bottom rail and resultant disengagement from its guide track is prevented by braces connected between the rear flanges of the bottom rail and the next uppermost horizontal strut.
