BSI 2120 Channel Balance 22"

Thanks for posting. This looks like either an S380-22 or S385-22. The only difference between these two types of 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. You will need a stamp option of 2120.

The top piece here can still be replaced by the one used on the Series 380 and Series 385 (our 19-005); despite the differences, they function essentially the same way.
