This wall section shows a vertical lift breakaway door assembly at a loading dock or drive-in opening. The door track routes upward beneath the roof structure, maintaining the required minimum clearance of twelve inches. The exterior wall panel transitions above the door opening, and the door height is coordinated per the schedule. The concrete slab and sub-base conditions sit below the opening.
