Window balance info

Hey there!

Thank you for your patience during our busy season. 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 also need a spring strength option of 1750.

If you have any further questions just let us know!
