BSI Channel Balance Replacement - Need help with part determination




Hi there!
I'm afraid I can't make out the end attachments on your channel balance. We can help but we'll need to see some close up pictures of your end attachments. Take a look at the video below, it explains everything we'll need to see.




Hi there!
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'll also need to weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.
If you have any other questions just let us know.
