Sliding door handle with lock

Thanks for writing in. I'm afraid I can't cross-reference these codes to anything in our database. In general, pictures of the old hardware is the best way to narrow down replacements. Is the handle set missing from the door? If so, we still may be able to help. Can you send pictures of where the handle set installs? Is there still a mortise lock in the door that the handle interfaces with? If so, can you show it to us? If it's not there, can you show us the cavity where the lock inserted as well? Finally, please tell us the distance between the center of each mounting hole to which the handle attaches to? That should help narrow down potential options. 

These photos are a huge help, thanks! I'm pretty confident that our 82-087 handle set will work for your door. You should review our specs just to verify, but otherwise please let me know if you had any questions or concerns. I'm happy to help in any way that I can.
