Looking for replacement window channel balance

A home owner from Irvine, CA says:

Please see attached photos. This is a 28 inch balance from an ALENCO window, approximately 30 years old. Info stamped into the balance = "c / 2730". I'm looking to purchase 4 of these.

Thanks for any assistance with this!

Take a look at our S395-28. See if this matches your old balance. You'll need a stamp option of 2730.
