I'm looking for replacements for both sides of window. I have additional photos if needed. The metal channel measures 1/2 inch and 29 inches long.
Thanks!

Hello,

It looks like you have either our S351-29, with a 15-002 bottom attachment, or S390-29, 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 2830 spring strength option for your replacement balances. Thank you!
