I have a S770 series 26 inch window balance with markings: 25DS 39 DX. I'm not sure what to order for a replacement. Your advice is appreciated.

Hey there,
Thanks for reaching out! This balance stamp does not cross-reference with those on our balances. To confirm the correct range for the replacement, I'll need to know the exact weight of the window sash.
Please let me know if you have any questions!
