Channel Balance

Question

Hi, I want to replace my existing channel balance. It is 28", width is 0.5" for a non tilting window. The engraved stamp states 27 4 BSI ND. The sash is 20lbs. I think I need the 28" Series 385 2740 but wanted to confirm. Pictures included. Thank you.

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 28" channel with a 2740 stamp option.

Please let me know if you have any additional questions!
