MIWA LB.100DAF+U1 Loss of key due to falling into elevator shaft

"Unlocking the entrance door by non-carrying a key"

I was told that she had dropped the key in the gap of the elevator shaft. This property in central Yokohama is a large apartment built this year. Since it is a new building, it is self-evident that it has a security thumbturn.

I confirmed that it was a crime prevention thumbturn by interviewing the client. Since the distance to the door scope is a bit close, I pay attention to my choice of tools.

I started by adjusting the distance with the shortest tool and extension shaft, but I had a hard time getting the tip jig stuck. Extending the scope hole to 13mm should be done thoroughly.

The improved anti-slip mechanism seems to work well. It is a good feeling. (All that remains is confirmation of the thin TM for GOAL GOE.)

After checking, it seems that there is a problem with the LED tool for the door thickness 40 mm fire door. There is room for improvement.
