Hello,

We'd be happy to help but we would need to see the top and bottom attachments on your channel balance to identify a suitable replacement. Thank you!

It looks like you have either our S351, with a 15-002 bottom attachment, or S390, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need a 2530 spring strength option for your 26" replacement balances and 3140 for the 32" balances. Thank you!
