Window Jam / Window Stop

thingiverse

I designed this window jam stop to keep my windows from wildly flapping open and shut when strong gusts blow past our building. It's specifically made for large windows that swing up vertically. By inserting this device into the window opening, it provides the necessary support to hold the window in place and prevents it from slamming shut with a loud bang. I've used it extensively throughout both winter and summer without any problems. While I'm not sure what its exact tolerance is since I don't have a way to test that, it has worked beautifully for me and our entire office without any issues.
