Abstract of the Disclosure A docking seal for a loading dock opening in a wall, comprising a rigid backing for attachment to the wall about the opening and a yieldable facing held dis- tended therefrom by air pressure introduced between the rigid backing and yieldable facing such as to form a continuous air chamber peripherally of the opening wherein the back wall of the chamber is constituted solely by the rigid backing and the front and side walls by the yieldable facing. The rigid backing comprises three frame members for disposition across the top and along the sides of the opening. The yieldable facing or flexible wall is attached along one of its edges to the inner edges of the frame member and along its opposite edges to the frame members at a location inwardly spaced from the outer edges of the frame members. The flexible wall is distended to define a continuous air chamber about the opening smaller in width and height than the opening, and the inner edge of the air chamber is substantially flushed with the inner edge of the frame members.
