Multiple parts for different windows

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. You'll also need 2640 spring strength options for your 27" long replacement balances and 2950 options for the 30" balances.

Thank you and let us know if you have any other questions or concerns.
