Question

...a friction shoe for my wood windows. I think it was a cardaco window, and I see that in other posts you've suggested a 15-104 friction shoe, however it looks like it is a little different on the top and i don't know if the back side fits on the same track or not.

Thanks for reaching out! This window shoe does appear to be the 15-104 Caradco Friction Shoe. While it does appear to be different, that could be due to the damage.

Ours is typically used along with the 20-016 Tilt Pin.
