I am looking for vent locks for existing vinyl windows that do not currently have vent locks. Can I install
20-013 on vinyl windows? I know that it says for wood windows, but I am wondering if they would work for vinyl and if I need to do anything special to install besides predrill. I know that drilling into the vinyl will void the window warranty, but I am not concerned about that at this point.
Alternatively, do you sell, or know of anyone who does, the vent locks that screw into the side tracks of the window?
