"I want you to lock your bedroom."
It seems that he is sleeping with his pet cat in the bedroom at night. Because of the GOAL LV lock, the cat who jumped on the lever and learned how to open it seems to go out of the bedroom without permission.
I proposed an auxiliary lock, but in the end it was a full set replacement.
I chose the LS-51 lock case for NAGASAWA made by WAKI, but since it could not be replaced as it was, additional work such as front part and hole processing was required.
The surface of this type of plywood type door is fragile, so the holes were machined from both sides, penetrated to prevent burrs, and carefully machined with fleas.
The lower hole filling process was closed with putty of the same color.
