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 a 2330 spring strength option for your replacement balance.

Thank you and let us know if you have any other questions or concerns.
