CONSTITUTION: An overhead folding door system using a standardized door panel comprises multiple overlaid door panels(150,151,152), height adjustment panels(86), and a height adjustment panel moving track(31). The overlaid door panels are formed by connecting upper and lower overlaid panels using hinges. The height adjustment panels are connected to the upper overlaid panels using roller hinges and are moved along the height adjustment panel moving track. |
