If you need further information, I'll try to get them.

Hello,

With this combination of attachments, you could have either the S380-27 or S385-27 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 2640 spring strength options for your replacement balances to support a sash between 19-26 pounds. Thank you and let us know if you have any other questions or concerns.
