Replacement Channel Balance

Hello,

It looks like you have either our S351-15, with a 15-002 bottom attachment, or S390-15, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. 

We'll also need to confirm the exact weight of your sash to determine the strength option needed for your replacements. Thank you!
