摘要
The present application is directed to a manual or automatic flush threshold door seal system used on folding exterior doors along with an alternate embodiment for conventional exterior entryway doors that will not impede the passage of a wheelchair. A flexible weather seal can be put in a retracted or down position within an aluminum extrusion imbedded within the threshold providing a flush access surface and may be raised up into the upright position providing an adequate weather seal.
