Channel Balance 23-1 BV CMC 2

Thanks for posting. The metal channel on the Series 800 is 3/8" wide. Measure the width of your existing channel. I suspect it might be 1/2" instead. If so, you need either the S351-24 or S390-24. The difference between these two balances is the depth of the bottom nylon shoe, so compare both with your old hardware to see what matches best. You will need a stamp option of 2320.
