Window channel balance

Hello,

We'd be happy to narrow down your replacement options but we'll need to see an unobstructed photo of the top and bottom attachments. Also, your stamp is part of an outdated spring strength system, so you will need to weigh your window sash and follow the chart on our product page once we determine the correct replacement you need to choose the correct option. Thank you!

With this combination of attachments, you could have either an S380-30 or S385-30 channel balance. You 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 You'll also need to weigh your sash to determine which option you'll need since your stamp is part of an outdated weight system. 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.
