Hello,

With this combination of attachments, you could have either the S380-26 or S385-26 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 2530 spring strength options for your replacement balances, which will support a sash between 15-19 lbs. Thank you and let us know if you have any other questions or concerns.
