I have a house full of these windows and one we use daily let go, I need to replace. Can you direct me to what the best part for replacement is? I don't see the "three number" designation on this box your website references.

Thanks for your post! This window balance can be replaced with the 24-737 Andersen Sash Balance. This can be used for balances marked with a 725, 727, 731, or 737.

It will work for both right and left handed applications.
