If hinge tampering is a risk you'd like to mitigate on your doors, typically one is faced with the reality of buying security hinges and re-hanging all your doors. However, the innovative Jamb Pins from Major Manufacturing achieve the same goal with minimal disturbance and downtime. Simply remove one opposing screw from each hinge leaf, drill a 3/8" hole in the jamb side of the hinge, and replace with a Jamb Pin. This will secures the door in the jamb when closed... even if an exterior hinge pin is totally removed.
For use on wood or metal doors and jambs. Jamb Pins have a combination of wood and machine threading.
