window balances

Quick Learner from Florida

Can you Identify this window balance? The metal piece is 22" long and 9/16 wide.

Thank you

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. 

You'll also need a 1440 spring strength option for your 15" replacement balances. The stamp on your 22" balances is a bit out of the ordinary so I would recommend weighing your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight. Thank you!
