Abstract
A loading dock shelter seal to the space between the sides of a truck and the door opening. The dock seal includes a pair of elongated flexible tapered foam members that protrude into the opening and contact with the rear of the truck. As the truck backs into the loading dock, the foam members deflect inward without deformation. This seals the sides because the foam members are vertically mounted on the sides of the door opening from the loading dock surface to a header curtain. The foam members are covered with a protecting fabric and have a retention strap system to prevent the fabric from billowing as the foam members deflect.
