Hello, Darra. This is a very old window, so you may not have a lot of options available to you. That said, I do wonder if our 39-398 stop device would suit your purposes. This is basically a little arm that you install on the sill that connects to the sash and prevents it from opening further than 45 degrees. The video below will go into more detail. Would this work for you? |
