Hello,

With this combination of attachments, you could have either the 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.

You'll need 2960 spring strength options for your 30" replacement balances. The 34-9 strength code for your longer balances is from an outdated weight system, so you'll need to weigh your sash to determine which option you'll need for the 35" long balances. There is a chart on the channel balance product page that explains how to choose your option based on the sash weight.

As for your top sash guide, take a look and compare the specifications of the 18-015 to your part. Thank you and let us know if you have any other questions or concerns.
