Hello,

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.

I would also recommend double-checking the length of your metal channel since the 28 2 code stamped on your balance normally indicate that you would have a 29" long channel. If so, you would need a 2820 spring strength option for either the S351-29 or S390-29 replacement balances. Thank you!
