The middle hole is meant to accommodate the thumb lever. It goes under the lock handle and right through it, into the mortise lock. Give it a try and see if that works.
Hello, my sliding door locking mechanism is fine, except the thumb flip lock on the interior door side broke. It has a slot the stub from the key lock slides in ans half of the broke off allowing the flip lock to fall off.
The whole handle pary # may be 22650. Can I just buy the little thumb flip piece amd the snap ring to hold it.on?
Thank you.
Mike
If you are speaking about the handle in the photo the prior customer posted, then that handle is no longer available. We do carry some lever thumb turns in the Patio door section on the web site, but not for the handle pictured. The only option we have to repair it is to replace it with a new handle set.
see 03/18/1950 post and response. I have the exact door handle and the same problem. What model new handle set do you suggest that would work and where can I get one.
Thank you,
Tom
