Looking for the correct channel balance size

Question

I had the channel balance break in two different window with the same size. I don't know the sash weight. The balance is 25" long and the plastic connectors look to be a fairly standard winged connector.

Hello, thank you for posting,

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 will need a 25" balance with a 2450 stamp option.

Please review and let us know if you have any additional questions.
