"I want to further improve crime prevention"
I replaced the cylinder last time. It is a KABA NEO that can only be copied from U9.
This time, it was decided to replace the normal thumb turn with a crime prevention thumb turn. Even after exchanging for KABA NEO, it seems that someone entered the room, looked around, locked the door, and left the room.
It seems that he has consulted with the police, but he said that he has continued several times.
Since it was an old model RA of stainless steel thumb turn, change to resin thumb turn body.The reason is that there are traces of crevice attacks.
NSL "DS-NLRA2-BTAC" for RA resin thumb turn was attached.After that, there seems to be no intrusion.
