MW Patriot Sash

Unfortunately, we find this happens when you tilt the sash in without raising the sash a few inches. Your sash is welded and you can't just replace the bottom rail. Not to mention, Patriot was bought out by Ply Gem and their windows series have been modified or replaced with the new company's design so chances of finding a replacement sash to fit your window is almost impossible. I recommend trying to contact a local Ply Gem dealer near you for a replacement sash.
