No LATthumbturn Lever operation unlock

It was a declaration that "a type that automatically locks like a hotel".

Judging the condition of the thumbturn from the position and type of bolt that can be seen through the gap.It's not clear when you check with the client.

I immediately try with an opener, but I have no feeling.When visually confirmed, it was a type without thumbturn.In that case, it would be fine to operate the lever.

It is always questionable whether such an automatic locking type is necessary for ordinary heights.

Change the tip jig to an appropriate one for Crescent, and the work is completed.
