Your channel balance resembles our S770-22. Take a look and see if you agree. If so, then this may be the correct part for you. Since your stamping does not match, any of our stampings, you will need to weigh your sash on a scale to get the exact weight number of the sash. From there, you will refer back to the product page to our sash weight chart to decide on the most appropriate option. This is the only way to determine the correct option.
