A recent thread mentioned a "string test" to check for plumb.

Doesn't that check just for parallel, not plumb?

"Plumb" means true vertical....the door frame sounds as if it is out of
plumb, front to back (or is it the wall itself?). Parallel means two
lines are equidistant from each other and can run any direction. The
two sides of the frame can easily be parallel but "out of plumb".
