Thus spake Timothy Lange:

Are you sure it is not a split jam that just pulls apart and you then install

the side with the door first, shim it, nail it, and then install the other
side and nail it? Mine are like that. Found a couple that were not nailed
on the non-door side.

Tim.

-=-=-=-

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,
