Need replacement lock assembly
Thanks for reaching out to us. I've seen this handle once or twice before, but the bad news is that we never found a perfect fit for it. The problem lies with the internal mortise lock: this is a very unique design that precludes compatibility with any of our available handle sets.
Before I say anything for sure, though, I'd like some more detail just so we can be certain of what we're dealing with. if at all possible, I'd like you to remove the mortise from the door and show me a clear photo of the hole that takes the handle's thumb lever. I'd also like you to tell me the distance between the two installation holes on the handle itself, center-to-center.
I can't guarantee that we can find anything for you but I will do my best.
Looks like your photos came in perfectly well. These are a huge help, too, I appreciate it! I'm sorry to have you jump through these hoops.
Looking at the hole spacing in your door and the design of your mortise, I think our 82-030 handle set will work for you. This isn't traditionally used with this kind of mortise, but I think that your case is a little unique. It seems that your mortise lock has a thin, 45 degree slot in exactly the right spot it needs to be to interact with a thumb lever like what comes with our 82-30.
While this may be an atypical application, our 82-030 should work perfectly well without having to change the mortise. This is my top recommendation.
Great! I'm glad you got everything working on your end. Please feel free to reach out if you had any other questions and I would be happy to assist you.
