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