Window channel balance 21"

Question

The metal piece alone, excluding the plastic end pieces, is 21" long. It only has "2030U" stamped on it, can you guide me to one?

Thanks for posting. See our S351-21 or S390-21 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Measure your old balance's shoe to see what matches best. In either case, for a new stamp option choose 2030.
