摘要： A high load retention system for a sectional overhead door enables uninhibited operation of a standard roller track mechanism of a sectional overhead door, while allowing high wind loads to be seamlessly transferred from the track mechanism to a more robust high load jamb retaining element. The system comprises: a plurality of primary door panels, each having a front face; a primary track; engagement elements each having a first end connected to a primary door panel and a second end that rides in the primary track; a high load jamb retaining element positioned adjacent to the primary track and having a clasping portion; and a high load door retaining element connected to a primary door panel and having a clasping portion corresponding to the clasping portion of the high load jamb retaining element.
