The Twist Combi4 is especially suitable for windows with a combination expander (in other words: expander) of 15 cm or higher. The window can still be opened and closed as normal, while maintaining the maximum 15 cm spacing prescribed by the police.
This product complies with the Poliekeurmerk Veilig Wonen® and SKG®
You can't imagine it, but an opening of 15 cm is enough room for many burglars to break into. It is not without reason that the police recommend that overhead lights (in other words: folding windows) be properly protected.
Practice shows that barrier bars have a very preventive effect. They are clearly visible from the outside.
A burglar doesn't even try to penetrate anymore.
Another practical convenience is that the window can remain open day and night for ventilation. A safe idea!
