Vinyl wiindow guide for tilt-out window

A home owner from Portland, Oregon says:
I have had a hard time trying to find this part in your extensive inventory.

The photos show the part with the broken piece.

I am not sure when the windows were installed - possibly the 1980s. Could not find any product information on them.

Much obliged if you can replace them; I need a dozen of them.

Thanks

Hello,

Your top sash guide reminds me of the 18-110. Take a look at the dimensions below to confirm if it's a match. Just let us know if you have any other questions and thanks for posting.

It is a bit hard to tell from the picture and to compare to the broken guides I have but it is by the far the closest fit so I have ordered 16. Thank you.
