Sliding door lock
I attached a picture of my old lock. I need to replace it
Thanks for posting. Take a look at our 82-259 mortise lock. This looks close to yours, but look it over and let me know what you think.
It has to be the same from the one I sent you.
Good morning, the 82-259 that we offered is a replacement option for your original mortise lock. The exact version of your lock is most likely not made anymore, but the only way to confirm this would be to reach out to your original manufacturer.
It looks similar to me, but I can't say for sure without knowing your dimensions. The patent number unfortunately offers no confirmation one way or the other. Like Kathleen said, there's a chance your exact part isn't made anymore.
We have detailed pictures and dimensions you can review on the store page to which I linked you. I recommend checking it out to see if our part is a match.
