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.

Hi Emily,

Thank you so much for getting back to me so quickly.

The part measures 1 1/8.

I have 9 windows to correct.

What parts and how many of each would I need.

Thank you
Margie

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!
