Your casing is already attached to the jamb with a 3/16″ reveal. This means no uneven reveals, just clean, straight edges.
Forget the classic way of hanging a door by shimming and mitering your corners. With a Prestoframe u-channel frame you have no shims, no miters to cut, and only time saved!
Still don’t believe? Watch the Prestoframe video to see how fast and easy they are to install!
