Hi there!

It looks like your balance is a match for the S380-25 or S385-25. You'll have to measure as shown below to determine the best match. Your old stamp is rated for 19 to 24 pounds. Are you having trouble opening and closing the window? If so, we recommend you weigh the window sash to see if it falls within this weight range.

Let us know if you note any discrepancies.
