Window Channel Balance with the markings 25 4 EX CMC 11

Thanks for writing in, Joseph. We're well, we hope you are also. This looks like either an S380-26 or S385-26 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. For a new stamp option choose 2540.
