Abstract
A curtain edge tensioning assembly comprised primarily of a portion of the curtain extending across the leading edge of the door. The curtain portion is releasably coupled to a guide extension extending beyond the leading edge of the door and engaging guide members to guide the door in a plane. The guide extensions also engage the guide members to restrict the guide extensions from moving toward the center of the curtain. The releasable coupling between these horizontally restricted guide extensions and the resilient member places a tension on the curtain portion. The curtain portion is thus stretched across the door, and serves as a wind retention bottom bar or edge that also substantially conforms to or deflects around an obstruction, thus preventing or minimizing damage to the door, the bottom bar and the obstruction.
