摘要： A fenestration system is disclosed. In some examples, the fenestration system includes one or more movable window sashes and a toggle assembly. In some examples, the toggle assembly operates to limit the degree to which the window sashes are opened or otherwise moved relative to one another. In some examples, a window sash may be opened a designated amount before the toggle assembly operates to obstruct it from being further opened.
