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.

A window security device includes a pull handle, the pull handle defining a tongue slot extending through the pull handle from a top paddle surface to a bottom paddle surface; and a locking bar slidably attached to the pull handle, a locking bar body of the locking bar positioned adjacent to the bottom paddle surface, a tongue of the locking bar extending through the tongue slot.

The present invention discloses a one-side rotating arc lock which comprises an adjusting assembly arranged on a first shell and a strainer arranged on a second shell. The adjusting assembly comprises an arc adjuster rotatably connected with the first shell. The arc adjuster is provided with multiple protrusions in the circumferential direction, used for adjusting the angle between the first and the second shell. Groove is provided on the protrusion. The strainer comprises an adjusting rod which matches the groove for locking the first and the second shell. The angle between the first and the second shell is adjusted through the arc adjuster rotatably connected with the first shell, and locking of the first and the second shell is achieved through the strainer. The one-side rotating arc lock of the preset invention not only has a simple structure and easy to operate, but also facilitates adjustment of the angle.
