Channel Balance 2740 Stamp

This appears to be either an S380-28 or S385-28 Channel Balance. The only difference between these two 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 2740. 

For the take out clips, see if our 16-002 match up.
