I recently purchased two replacement operators (39-028E & 39-027E). They fit nicely and will work with the windows. However, the plastic wheel on the end of the new operators did not match the existing tracks. The old tracks and old operators had the thin, flat plastic wheel. Now I need to replace the tracks with something that will fit the new operators.
The old track is 14" long and has three holes for mounting. I'm not sure which track from your selections would be the best one to fit the 39-028E & 39-027E.

Thanks for posting! The 39-027E and 39-028E are meant to work with the 39-533 track. Look over its measurements and style and see if you could mount this on your casement window sash.

Thank you for the research and response. I will give the recommended track a try. I'll probably have to adjust where the track is mounted but that shouldn't be a problem. Again, thank you.
