Abstract
Overhead door guide assemblies, guide tracks, and guide track support brackets are disclosed herein. An overhead door track assembly configured in accordance with one embodiment of the invention includes a vertical track segment mounted to a wall adjacent an opening therein, and a curved track segment operably coupled to the vertical track segment. The curved track segment includes a first guide surface spaced apart from a second guide surface to define a first gap region that movably receives the door guide members as the door moves away from the opening. The track assembly further includes a non-vertical track segment operably coupled to the curved track segment. The non-vertical track segment includes a third guide surface spaced apart from a fourth guide surface to define a second gap region that movably receives the door guide members from the curved track segment. In this embodiment, the second gap region is wider than the first gap region to reduce binding as the door moves onto the non-vertical track segment.
