Summer vacation is coming soon. I think that many families will be away for a long time when traveling or returning home, but isn't the key to the window left anxiety about crime prevention? I found a product that seems to be easy and effective at the 100-yen shop "Ceria", so I tried it.

An item called "NEW Window that does not open" sold by a manufacturer called Mitsuki. Auxiliary lock for windows that prevents the window from opening easily by installing it on the sash part of the sliding window.


A mechanism that prevents the window from slipping by sandwiching two stoppers in the groove of the inner door. When you turn the knob, the stopper moves and you can adjust it in the range of about 28 to 42 mm according to the size of the window.




There are black and silver colors, and if you match the color of the frame, it will be almost inconspicuous. In addition, it seems that the crime prevention effect will be further improved by installing two on the top and bottom of the window frame. Overconfidence is prohibited as it is an auxiliary item to the last, but it is said that if you can gain even a little time at the time of invasion, it will give a psychological burden to the burglary.



Also, if you open the window and open the screen door in hot weather, you may be worried that you may be invaded from the outside or your child may open and go out to the balcony. When I tried using the product with the window open, I was able to fix it in the same way (it is originally used in the locked state, so at my own risk. I use it at night or leave the window open. Please avoid).


A "window that doesn't open" that even women can easily install because it doesn't require any special tools. Why don't you try it at this time when the crime prevention consciousness tends to fade due to the heat? The price is, of course, 100 yen (excluding tax).
