ABSTRACT A suspension system for a heavy duty industrial door has a double guide track system which provides smoother operation and resistance to jamming due to the effects of wind or negative air pressure. Respective guide tracks can be disposed at 90° angles, and a similarly designed support carriage having a pair of traveling support devices disposed at right angles engage each of the guide tracks for supporting associated sections of a flexible door. The suspension system according to the invention is particularly adapted for use with folding industrial doors which comprise a series of overlapping flexible plastic strips which depend from hinged rack sections.
