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. 

Is there a stamp on your metal channel? If not, you'll need to remove and weigh your sash to choose the appropriate spring strength option. There's a chart on the S380 and S385's product page that shows you which option you'll need based on the weight of your sash.

If you have any further questions please let us know.

Thanks for your help. Ordered (4) 35" Series 385/3430.
Channel was marked 34 3 FR Caldwell, I'm assuming that meant 3430 weight? Let me know if that's incorrect and we can modify the order. Thank you. Dave B

Hi, Dave.

Yes, that's correct. If the stamp on your metal channel reads " 34 3" then you would choose the 3430 spring strength option.
