Milgard Channel Replacement

Thanks for posting. Your balances look like they could be our S351-21 or our S390-21 with a 2040 stamp.

To determine which balance you have you'll have to confirm the measurement for the depth of your bottom shoe. Use the diagram below for reference to confirm the measurement. Let me know if it does not match either of these.
