Channel balance ID

Question

Hi, I want to replace my existing channel balance. It is 27", width is 0.5" for a non tilting window. No engraved stamp. I think I need the 27" Series 380, not sure about the sash weight but wanted to confirm.

Thanks!

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.

Since your balance doesn't have a stamp code, you'll also need to weigh your sash to determine which strength option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.

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