Hello,
I need help on identifying the proper channel balances for my windows. I have 2 difference size windows with different size balances. The large window has 28" and small ones have 22" channel balances. I have 1 large window and 2 small ones to replace the balances. I have detailed information and images in the attached PDF files. Please let me know if you need more info.
Thank you,
Thi

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 also need 2740 spring strength options for your 28" replacement balances and 2140 options for the 22" balances. Thank you and let us know if you have any other questions or concerns.
