[Ventilate while taking measures against window crime] "I want to ventilate, but I'm worried about leaving the window open." This "auxiliary lock for sashes" solves that problem! Even in homes with children who have learned to open the window locks, you can ventilate while preventing them from going out onto the veranda, so you can rest assured. You can lock the window frame with the window slightly open, so it can be used as an intermediate stop for windows with air conditioners or ventilation fans installed. It is also convenient for ventilation in various places such as the kitchen, shower room, toilet, and living room. However, the security effect will be reduced.
