Abstract: A sealing assembly adapted to close the gap between the swinging edge of a door and an associated member. In one embodiment the sealing assembly includes first and second generally cylindrical elements having a plurality of spaced apart teeth which extend radially outwardly from the elements, and first and second mounting means to mount the elements for free rotational movement in such a manner that they are parallel with each other and the edges of the associated structure so that when the door is closed the teeth of the first and second elements will interengage with each other.
