Hello, Operators are not meant to limit the range that the sash can open but we do offer the 39-398 sash stop device. This may work for you but keep in mind that it's designed for casement windows rather than awning windows like yours. I don't think that it would be a problem in this case since it would serve the same function but it's something to keep in mind. Take a look at the video below that shows how this part installs. Thank you! |
