Need replacement balance

Question

Seems to be 21" by 1/2", but I can't seem to find an exact match.

Thanks for posting. See either the S380-21 or S385-21. The only difference between these two channel balances is the 'depth' of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 2040.
