Hello,

With this combination of attachments, you could have either the S380-30 or S385-30 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 2940 spring strength options for your replacement balances.

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