My balance part 26 9 34# HO CALDWELL is 27 IN X 3/8 IN (approx) metal part with plastic ends. See photos.
Thank you!

Thanks for posting. I recommend either our S385-27 or S380-27, I'm just not sure which. The key difference is the bottom shoe; you will need to measure yours to determine which balance is a better match.
I also recommend weighing your sash on a scale to confirm the correct option.
