Porter-Cable 59370 Door Hinge TemplateMost of the other reviewers are correct that this is an inferior product. I'm a professional trim carpenter. Others have pointed out that the jig does not size the mortise correctly and that is absolutely the case. I had to spend a few minutes shaping the radius of the template with a rasp and also shim the opening slightly smaller so that I didn't end up with unsightly gaps around the hinge. It's a cheap product, but even for the price it doesn't work well enough to justify buying it.
