Abstract
One end of an internal barrier assembly is attached to a forward side of a cabinet below a door of the cabinet by bolt and nut fasteners threadably assembled together at the exterior of the cabinet to be readily visible to an observer inspecting similar bolt and nut fasteners for the cabinet door, all such fasteners preferably being disposed on a common face of the cabinet. The bolt and nut fasteners have holes therein through which a wire loop of a lead security seal is wound and the integrity of all seals may be visibly observed without opening the door.
