An articulating door is fixed to a torque tube through a plurality of structural tube elements and gussets. The torque tube is rotatably fixed to the building. A sprocket, which is engaged to the torque tube, is driven by an electric motor and gear reduction drive, and a chain reduction drive. An arm assembly and counterbalance element counterbalance the door as it moves between its open and closed positions. In its open position, the door remains folded exteriorly of the building.
