Prepare to be amazed!
In their attempt to put a thumbturn on the inside of the door (often for fire-safety regulations) they made their averagely secure locks, useless. Why? Because you can put this tool through the lock and engage the cam directly.
Yes, that's right - meaning you can open the lock with ease. Thumbs up to that!
If you encounter a lot of thumbturn locks in your work - these are a MUST!
This set covers the most popular type in left and right keyways.
