Out of plumb (also referred to as twisted) frames usually cannot be adjusted.
"Out of Plumb or Twisted frames (or jambs)" is a condition created by improper wall construction and/or improper installation and anchoring methods. The faces of the two jambs (hinge and strike) are not in the same imaginary plane as discussed in the twisted door section. This can be checked by using a level and/or plumb bob. Frames do not have adjustments when it comes to “twist”.
The “twist” condition is generally caused by the wall conditions. The frame jamb faces are prevented from being set in the same plane because the base of the walls (the bottom at each jamb) are out of plane to begin with.
It is the responsibility of the installing contractor to install walls and all door/frame material in accordance with SDI or HMMA installation standards and tolerances. Frames which are installed in out of plumb walls which exceed the published tolerances must be adjusted or replaced by the installing contractor.
More information on "out of plumb" frames can be found in SDI-122 which can be viewed here.
