What is the proper way to handle a split Jamb prehung on a 2x3 wall?
I just finished installing a prehung door on my 2x3 wall. I put the door side in like normal, then I cut 1/2" off the insert part of the split jamb all around with a jig saw and it slid right in. I know some people using some kind of furring for the casing like a 1/2 strip of molding or something. I like the fact that the way I did leaves the door looking normal. What is the "proper" way to handle this?
