For as long as I can remember, people in our industry have had some level of discomfort dealing with doors. On the supply side, we struggle to get our heads around a category with seemingly endless options. On the contractor side, it can also be worrisome, as the same myriad of choices stares you in the face, and it requires proper research and communication to end up with a quality solution. Once you do get the right door to your job site, you are tasked with performing a quality install for your client. Of course, you're also committed to standing behind your work.

To help with this issue, our friend Gary Katz (of Katz Roadshow and THISisCarpentry) put together a video and article on installing problem-free prefit doors. In these resources, Gary covers how to prepare the rough opening, ways to correct cross-leg issues, the placement of screws, and the location of shims. Gary goes through his exact process—because the order of installation is crucial to a smooth install. His process also allows for adjustments at a later date with nothing more than a screw gun. We were so impressed with Gary's video, we created a brochure outlining his process, which you can see below.
