WIndow balance is 1/2 inch wide and 25 inches long. Marked with Caldwell 24 4 FK. Which replacement part do I order? Thank you.

Hey there!

It looks like you have either our S351-25, with a 15-002 bottom attachment, or S390-25, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You will also need a spring strength option of 2440.

if you have any further questions just let us know!
