Opening Width Restrictor

Opening width restrictors are commonly used in windows as a safety feature. They allow the window to open only to a predetermined angle, ensuring, for example, that it opens just wide enough for a child-without allowing them to climb out. This provides peace of mind for parents, especially in upper-story rooms, knowing their children remain safe even without direct supervision.
In commercial settings, such as hotels, restrictors help prevent accidents by reducing the risk of someone falling out. They also protect the window from being forced open or damaged by strong gusts of wind.
