Unlocking the dressing room empty lock

"I want you to open the dressing room"

I was surprised that the spindle shaft that connects the levers was threaded.

When I unlocked it, it was MIWA's LO empty lock.

I made an estimate with a combination of NAGASAWA's empty lock and an optional lock case, but it was also canceled.Therefore, the work is completed only by unlocking.The main body case was removed as an unnecessary part.
