U9.RVH (RA type) Unlocking the entrance door with 64 type lever handle

"Lost key, Unlocking the entrance door"

Is it a public corporation or a housing complex property? Take the stairs up to the 4th floor. As always, tool bags weighing over 10kg are heavy.

At first glance, it looked like a U9.RA type, but it is a lock with a distinctive handle. Although I rarely encounter it, the security thumbturn B5 type was the standard equipment type.

When I did a one-shot with normal unlocking, I noticed something strange. I totally forgot.

Replaced with a special tip jig and completed with special unlocking. Even in public corporations, there are quite a few people who switch to this type to improve crime prevention and as a barrier-free measure with a large lever. However, you will need to put it back when you move out.
