ABSTRACT:
A loading dock seal with an adjustable top seal for providing a weather-tight seal between a loading access opening of a loading dock and vehicles of various heights which includes a compressible pad means surrounding at least the vertical sides of the opening and made of a durable yet resilient material to provide a weather-tight seal on opposite vertical sides between the pad and the vehicle being unloaded. A curtain means, attached at its upper edge above the loading access opening and at its lower edge to a tubular top seal, is of sufficient width to cover the opening. The top seal is vertically adjustable from a storage position above the opening to a sealing position upon the roof of the vehicle thereby combining with the curtain to provide a weather-tight seal between the building and the vehicle.
