A sash window stop in installed onto the top section of a sash window. There is a barrel that stops the window from being opened past a set point. You need to choose that point when installing the sash stop.
There is a protective keeper that is installed on the top of the lower section of the window, to stop the timber of the window from being damaged when the barrel hits it.
The barrel can be fully retracted to allow the window to open completed when desired. Sash Stops are a great safety option for children, especially for second story windows.
It is recommended that two sash stops are added per window, they are available in single or packs of 4.
