Hello, It looks like something is not lining up properly in your door. Looking at your photo of the mortise lock, I see that the mounting holes are blocked. Maybe that internal mortise lock is not installed properly. You may want to try removing it and reinstalling it to see if that helps. The mounting holes of the handle set for an assembly like yours are normally 3-15/16" but you should measure yours to be sure. Also, take a look at the suggested parts and videos we've related for you that should help get you on the right path. Thank you! |
