ABSTRACT:
A bulkhead door for watertight closing of a bulkhead opening of a naval vessel, comprising a composite outer shell and inner shell, a chamber therebetween, and a channel along the door margin for retaining a gasket without adhesive. The chamber may be filled with a material such as a rigid foam to increase door strength and rigidity. The outer shell includes hinge blades spaced apart by a standard distance and spaced equally from ends of the door, so that each door may be used for either a right-hand or left-hand bulkhead hinge pin orientation. Metal strikers are bonded to the outer surface of the door for engaging closure dogs in use. A door may be provided without any strikers, and the strikers then bonded to the door at appropriate locations during installation of a door to a specific bulkhead opening location.
