Channel Balance Caldwell

Question

I am pretty sure I need the 33 inch series 385 channel balance. The only other one that I am considering is the 33 inch series 380 channel balance. Do you think I'm on the right track? I see that the only difference between the two is the depth of the shoe, and I think the one I have is the longer one. I appreciate any help/insight, thanks!

Hi there!

I agree! With this combination of attachments, you could have either an S380-33 or S385-33 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 remove and weigh your sash to choose the appropriate spring strength option. There's a chart on the S380 and S385's product pages that will show you which option you'll need based on the weight of your sash.
