When required, it is possible to “spring” the door back to (or much closer to) its ideal position of being parallel
with the imaginary plane across the faces of the frame. This can usually be done with the door remaining in the
frame. A piece of wood blocking must be placed between the door and frame. Pressure is then applied at the
twisted area to “spring” the door. However, caution should be exercised on drywall installations since the frame
could possibly work lose from the wall, particularly with slip-on drywall type frames.
