ABSTRACT:
An adjustable door stop system and method for a hinge mounted door having at least one hinge leaf connected to the door and at least one hinge leaf connected to the doorway. The door stop system includes a hinge pin having an axis about which the hinge leaves rotate. A first disk extends radially from one end of the hinge pin. A second disk has an opening to receive the hinge pin therethrough. A finger extends from the first disk substantially parallel to the axis of the hinge pin. A finger also extends from the second disk substantially parallel to the axis of the hinge pin. The first disk finger engages the hinge leaf connected to the doorway and the second disk finger engages the hinge leaf connected to the door to thereby stop movement of the door without contacting either the door or the doorway.
