I have a Sunair window Balance w/2740 B.S.I stamped on it. I am a bit confused as to which series to get 350, 380 they all seem to have the same specs and end pieces. Thank you.

Good Afternoon,
A lot of the channel balance series do look very similar but there are differences between the balance attachments. The balance attachments are the plastic (sometimes other materials) attachments found on the bottom and top of the channel balance. If you need help choosing the replacement channel balance series that matches your existing balance, please submit a couple pictures of your channel balance's attachments. We can help you choose the proper balances series based on your pictures.

Can you confirm the length of the channel portion of your balance? I think it may be 28" in length.

This appears to be the S350-28 Channel Balance with the stamp option 2740.
