I am hoping you can help me identify this top sash guide. We don't know the window brand. Please see attached photos. Kitty

Your top sash guide looks similar to our PGT 4000 Series Top Sash Guide, the 18-015. Are you just using the top hole to install on sash? If so, this should work nicely for you.
