A high-speed sectional overhead door covers a door opening with panels stacked in a single plane and lifted from the bottom-most panel. As panels are lifted, each rolls in its own individual track. As the panels move into the head area, they run through curved tracks and are nested there. The stored panels stacked horizontally one atop another with the door open. This design utilizes a dedicated panel-track pairing as well as a unique hook/cam device which allows for the upper panel to be both locked in the closed position and pushed away for separation and storage in the open position. The design also provides a sectional door with low headroom clearance, high speed closing/opening and a multitude of panel heights without hinges joining the adjacent panels
