Thank you! This part is known as a top sash guide. We can help, but we will need to see yours out of the window in order to identify it. Knowing its dimensions would also be a huge help. In the meantime, you can see our entire selection here. You may also find the video below helpful.

Looks like the Kinco top sash guide, 18-044. Please compare sizes. Is it right?
