Channel Balance Replacement

Hello,

It looks like you have either our S351-34, with a 15-002 bottom attachment, or S390-34, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. You'll also need 3350 spring strength options for your replacement balances. Thank you!

Comparison of the S351 and S390 balance shoes.

The stamp code indicates the tension of the spring but, unfortunately, not the correct replacement. Once you determine the correct balance series based on the depth of your shoe, you'll select 3350 strength options to support a sash between 28-32 lbs.
