Mortoise lock match

Thanks for posting. Just to clarify, we don't manufacture doors or parts; we just offer replacement hardware that is used by a wide variety of brands. That said, this handle set does indeed match our 82-086. Without seeing your old mortise lock or at least the hole in the door it fits into, I can't say with total certainty what you have; furthermore, the 82-086 works with a few different types. That said, the issue of the lock falling into is almost always linked with the 82-218 mortise lock, which is indeed compatible with your setup. Take a look and see if you think this might be what you need.
