Hello,

It looks like you have either our S351-32, with a 15-002 bottom attachment, or S390-32, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to weigh the sash and follow the chart under the product description to choose the correct spring strength option for your replacement balances. Thank you!
