ABSTRACT:
A dock seal header to be secured over a doorway in a loading dock. The header includes a panel or sheet of flexible material having an upper edge which is secured to the dock above the doorway. The header extends down to partially enclose the upper end of the doorway. A plurality of horizontal slabs or bars of a compressible material, such as foam plastic, are mounted in vertically spaced relation to the panel. A cable and pulley system is attached to the lower edge of the panel. The panel can be pulled up to a generally curved configuration through the cable system and is adapted to drape against the top of a truck parked in front of the loading dock. The side edges of the header panel are connected to the header pad cover by releasable fasteners, such as a hook and loop arrangement. As the panel is pulled upwardly, the fasteners will release and as the panel lowers, the fasteners will automatically re-engage.
