Non Tilt Window Replacement Channel

Question

This piece is on the top of the window frame and I think it holds the top end of channel.
It is broken for a couple of windows.
Can you please identify this part.

Thanks for your patience during this busy season. Start by looking at our 18-166, or perhaps our 18-009 as well. Compare the dimensions to your old top sash guide and see what matches best.
