trying to replace channel balance. need insight to buy the right one

Question

This one measures 17 inches. I have a bunch of different lengths but the ends are all the same. I wanted to start with this one to make sure I'm going the right direction.

Thanks,

Hello Jim,

It looks like you have either our S351-17, with a 15-002 attachment, or S390-17, with a 15-001 attachment, channel balance. Take a look at the image below to determine which balance you'll need. You'll also need to know the weight of your sash in order to choose the correct option from our product page. Thank you!
