Counter Balancers

Hello,

It looks like your balance has non-winged end fittings. If so, you could 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 2140 spring strength option for your replacement balances. Thank you!

Great!

Please see the S390-22 channel balance with a 2140 stamp option. The length of the metal channel excluding the nylon attachments should measure 22 inches long. Let us know if you have any additional questions!
