Sliding glass door lock

Question

My wife manages rental properties and in one of the units the sliding glass doors is missing the lock and lever. It is a Mortise lock system. She bought one replacement and it didn't fit. I tried a second replacement and it didn't fit either. The drill holes are at 3 & 11/16 inch. The ones that I have tried for the part of the lock that actually goes in the whole in the door were 3 & 3/16" and 3 & 1/8" both are to big to fit the rounded hole. I have not been able to find a smaller size. The only stickers on the door seem to indicate the type of door when I google it. SGD-R-72x80. Any idea what part I need?

Hello there!

Thank you for reaching out to us. I'm afraid I don't know what part you may need from this description. Can you show us some photos of the handle set and mortise lock? That's the best way for us to help.
