Hi Couldn't find by searching unfortunately, so wonder if some of you experienced folks may be able to help. I am looking for either some self-install windows locks/limiters (idealy the latter) that restrict how far the windows can open ( I need kinds for both casement and sliding windows) or a contact for a contractor who can do this please. For casement windows I know there is a way to drill into the frame and screw in a small rectangular flat piece of metal that can restrict opening, but not super keen on doing this myself and screwing up my window frames. For sliding, I came across a Sellery product but can't seem to find it in any shops. Can anyone help please? Thanks
