Hi! I am trying to find the right top sash for my windows. I didn't see them on your site, but hopefully my pictures will help you identify them. These are from a house that was built in 1985 and these are the original windows. Thank you.

Start by looking at our 18-061 Pennco Top Sash Guide. Please look it over and see if you think this could work for you.
