Hello, With this combination of attachments, you could have either an S380 or S385 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. I also agree that you'll also need 3550 spring strength options for your 36" replacement balances to support a sash between 30 and 35 lbs. If your 30" balances have worked well up until now, you'll need 2950 strength options. Thank you and let us know if you have any other questions or concerns. Comparison of the S380 and S385 balance shoes.
