ABSTRACT:
A fiberglass bulkhead door assembly includes a bulkhead enclosure for mounting on a bulkhead, at least one door and top and bottom hinges for mounting the door to the bulkhead enclosure. The bulkhead enclosure includes fiberglass side walls, a sloping fiberglass top wall and a tie bar connected between the side walls. The top wall has a door opening. The door is movable between a closed position covering the door opening and a open position providing access to the bulkhead. Each of the hinges includes a fixed member attached to the bulkhead enclosure and a movable member attached to the door. The fixed member of the bottom hinge is rigidly affixed to the tie bar so as to transfer stress to the tie bar during opening and closing of the door.
