Abstract: A hinge includes an elongate connecting knuckle to which a door flange and frame flanges are pivotably attached. The door flange has a plurality of symmetrically located screw holes such that the screw holes are in alignment with screw holes formed in a door in use with the frame flange disposed on either side of the door, resulting in a reversible hinge enabling the door swing to be changed from a left-hand to a right-hand door swing or vice versa. The hinge is for use with a hinge reinforcement plate or stand-off plate which includes end portions and a centre portion offset relative to the end portions. Hollow self-clinching spacer pieces extend from the underside of the stand-off plate. The spacer pieces include internal threads and are embedded into the door frame in use and provides means for securing hinge screws through the door frame.
