I've installed the new jamb, however the new jamb appears to bow a bit, and goes in quite a bit at the bottom. I haven't screwed it down yet, or shimmed it, I wanted a second set of eyes (and 3rd, 4th, 100th) to make sure I didn't do something wrong.
Okay, I apologize for the lack of information given here. To expound, my wife locked the door and closed it behind her before checking to make sure she had her keys, and broke the door frame somehow to retrieve her keys.
So, only the strike side really needs to be replaced. I removed the molding and the old jamb, and bought a new kit from Big Box.
Also, the wall is plaster. From what I've read, plaster door jambs and drywall door jambs are different sizes although we measured thickness of old and new jambs @ Big Box, a quick check of width shows 5 1/4" on the old jamb, and 4 1/2" on the new jamb.
Is there any way to use this smaller jamb? I don't think they have larger ones in stock.
