Window Balance

Hello,

With this combination of attachments, you could have either the S380-35 or S385-35 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 3450 spring strength options for your replacement balances. Thank you and let us know if you have any other questions or concerns.

As for the take-out clips, you can start by comparing the specifications of the 16-002 commonly used with this type of balance assembly. Thank you!
