OK so I got about 20 interior prehung 6-panel doors with trim from Lowe's for $50 a piece. I was buying a lot of stuff they wanted to get rid of. Now putting up 8 news doors in a house. All of the jambs are 4 inches...
Well when I bought the doors they told me that they were fine for 2x4 construction. Didn't tell me that it would be 2x4 with 1/4 inch drywall. The problem is that I have 1/2" drywall, making the jamb a 1/2 inch too wide.
Are the 4 inch jambs common and what is the easiest way to add the outer strip?
