Hinge Doctor® is designed to adjust new, worn, or improperly adjusted hinges that cause the leading edge of the door to hit the side of the door frame (above the strike), when the latch no longer lines up with the strike hole, or when the door shows excessive signs of dragging or sagging.
To fix the door, simply slip the Hinge Doctor® over the top hinge and turn with a wrench. This action causes the door hinge to bind while the tool is in place. It is usually only necessary to adjust the top hinge.
For model HA2 "The Hulk": Simply slip the Hinge Doctor® over the hinge, tighten the Allen head bolt and rotate the Hinge Doctor® toward the door lock. Done! Adjusting the bottom hinge is not recommended.
