threshold (or sill plate) which requires removing part of the built-in door stop at the bottom of the door. My threshold was rounded rather than a simple slant as illustrated, so I had to carve the curve with a utility knife (NOT EASY!), only to discover I had removed too much material from the outside edge of the jamb. Luckily, I'd saved the pieces I had cut out, so I simply modified them and glued them back in place with PVC cement..
My only other problem was that the long sides of the jamb are pretty flexible, so you have shim them along almost the entire length of both sides of the door or they will bend out of proper alignment. The wooden jambs I've installed are not nearly so flexible. All in all though, I very pleased with the final results and the door fits perfectly into this new jamb.
