Sliding door lock.




The thumb lever can likely be replaced with our 82-107; review to confirm. To know what mortise lock you need, you'll have to remove it from the door to show us. From there we'll ID it for you.

Thanks

Hello, Scott! Your mortise lock is actually kind of weird. We have one in particular that is similar, our 82-226, but the face plate on ours is round, not squared off like yours. That squared off face plate is definitely a road block right now. We just don't have anything like it.
We might be able to drive around it, though. Consider our 82-218. I believe you can use this to replace the mortise in your door and simply reuse the same face plate. Would that work for you? Look it over and see what you think.
