Finding correct Channel balance

Question

Not sure what make the window is.

The spring stopped recoiling on one side. I will replace both. However I'm not sure which part to purchase.

Thank you.

Hello,

With this combination of attachments, you could have either an S380-23 or S385-23 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 2230 spring strength options for your replacement balances.

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