Abstract
An improved hinge for supporting a door on a door jamb wherein the jamb leaf of the hinge is provided with an extended part having a buck pin that is offset from that part of the leaf aligned with a door edge so that the pin is insertable in an aperture provided in the strongest part of the wall behind the door jamb. The jamb leaf is secured to the door jamb by screws located at the extended part of the leaf, i.e., outside the area covered by a closed door, and a protective cover is provided to prevent access to the screws after the leaf is secured to the door jamb.
