Adapted for wooden window frames thickness 35mm - Please confirm the dimensions of your window frame before printing

This window blocker allows to keep the window open ~5cm and secure it in place.

• The U shaped part slides in place on the "mobile window"
• The round shaped portion fits into the groove of the "fixed" window which can be locked.

No screw, no glue, no modification of the window frame !

This is my original design, if you appreciate it, please like and share... I will do more !

Cheers from France

IMPORTANT : The product is very sturdy but definitely is not a safety device : THis is not meant to be robber proof nor child proof. I designed this to aerate my home, please print and use at your own riks ;)
