window balance

Thanks for posting. See our S380-33 or S385-33. The only difference between these two channel balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. See the diagram below for reference. In either case, for a new stamp option choose 3240.
