With this combination of attachments, you could have either an S380 or S385 channel balance. You’ll need to measure an undamaged bottom attachment from both balances 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 1530 and 2740 spring strength options for your respective replacement balances.
Thank you and let us know if you have any other questions or concerns.
