Hello,
With this combination of attachments, you could have either an S380-24 or S385-24 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need to locate the stamp code on the metal balance channel to choose the corresponding strength option.
Thank you and let us know if you have any other questions or concerns.

Thanks. The measurement you are referring to is 1". The stamp code I see on the metal balance is 2390d (B.S.I) 29
Does this match anything you have?

It sounds like you need the S380-30 channel balance but your stamp code is from an outdated weight system. I'd recommend weighing your window sash and following the chart under the balance product page description.
