Abstract
A closure includes a hub having a bore in fluid communication with the port of a vessel. A door is removably positioned within the bore of the hub, and a locking ring is threaded with the hub thread for moving the door to a closed and circumferentially sealed position against the shoulder. At least one rotatable actuator element, such as a plurality of gears, engages the locking ring and is rotated to rotate the locking ring. A breaker bar or impact wrench could be used to rotatable drive the actuator elements.
