Sliding glassdoor two point mortise lock

Your mortise lock reminds me of the 82-265 Multi-Point Mortise Lock. To determine if this is the correct replacement, you'll need to carefully review and compare the specifications. When measuring, you will need to confirm the distance between the installation holes on the face plate.

There is a chance your existing keeper may not be compatible with our mortise lock. That said, you may need the 82-249 Sliding Glass Door Multi-Point Keeper. The specifications for it can be found on the website.
