side and nail it? Mine are like that. Found a couple that were
not nailed
on the non-door side.

Lo an' behold! It is a split-jamb.

But the question still rears its head: how do you install the shims
to give
you a plumb-and-square install, when the casing is already nailed to
the
(half) jamb? Access to the space between the rough opening studs and
the door
frame is accessible from only one side (the non-casing side).

Ideas?

Thanks,


All of the weight is on the hinge side of the door. Hang that side
first, shim and level it. With the door on, set the head and the side
jamb to the door leaving 1/8 space on all sides. Shim as needed.
Install the other side of the jamb, face nail the casing and then nail
through the stop to secure the two jamb sections together.
