Handle Install Issue

Question

I need to find a locking mechanism that is compatible with pre-drilled holes in door frame. It seems that this lock in blocking the holes, making it complicated to screw on new handle. Pictures client sent me that I have attatched, show what the problem likely is. You can see old the old and new handle sets. Client may also need a different handle with screw holes closer together, that will also match holes in door frame. Help would be much appreciated, thank you in advance.

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!
