There are no numbers or stamps on the old balancer. They are 18 inches long. Can you tell me what balancer we need? I need 8 of them

Hello,

It looks like you have either our S351-18, with a 15-002 bottom attachment, or S390-18, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need to locate the stamp code on your metal channel to choose the corresponding spring strength option for your replacement balances. Thank you!
