Product 82-016
Hello there. It's very difficult to say without more information. Can you send us photos of the existing handle sets? We'll do our best to help from there.
Thanks for getting back to me. Based on the shape of the locking tooth, I wonder if you actually have an older version of the 82-055 Handle Set, which also has a 3-1/2" hole spacing. See below. Now, we don't carry 'dummy handles' for these handle sets, so if you need to replace the handle set on the non-operating panel as well, the best we could offer is you using another one of these handle sets and just 'gutting' the locking mechanisms. It's not ideal but it's the best we can offer. See what you think.
I meant if you are looking to replace the handle set on the other sliding door. Presumably this one has no internal locking device; it's just there to have pulls to move that panel. You likely could use the 82-003 in that case, but you'll have to discard the internal lock, since it has no purpose. I hope that makes sense.
This entire design is an older style that was phased out. The 82-003 is the most modern design we have.
Sounds good. If you need anything do not hesitate to ask!
