ABSTRACT:
This invention relates to a sealing device for flexible closures for building openings, especially aircraft hangars, gymnasiums, etc. The device comprises elongate flexible sealing gaskets located alongside and substantially coextensive with each of the vertical building members on each side of the opening. The gaskets decline inwardly toward one another and each has a convex outer surface, which is skewed outwardly from the opening. The gaskets contact the flexible door along its vertical edges to seal it when closed and assist in preventing wrinkles or uneven winding of the flexible door on its roller.
