Abstract
An improved butt hinge is disclosed in which each hinge half comprises a leaf portion formed integrally with a butt strap. A second leaf portion mounts to each butt strap after the butt straps are mounted to a door and door frame. A hinge pin passes through each of the four leaf portions to hingedly mount the door to the door frame. The hinge pin cannot be removed without removing at least one of the second leaf portions, and since the second leaf portions cannot be removed while the door is closed, the hinge pin cannot be removed while the door is closed.
