Hi, Margie. It looks like you have either our S351-22 , with a 15-002 bottom attachment, or S390-22 , 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 spring strength option of 2120. If you have any further questions just let us know. ![]() Comparison of the S351 and S390 balance shoes.

No problem, Margie! If your bottom shoe measures 1-1/8", then you'll need our S390-22 . As for how many you need, it depends on how many balances you have in your sashes. Let me know if that helps! |
