Hello Michael. For the the S770-20, a stamp code 2000 should conform to our stamp option of 20C, which supports a window sash that weighs 14 through 18 lbs. For a stamp code of 2801, I believe you can use 28D, which supports a sash in the weight range of 23 through 28 lbs. Let me know if you have further inquiries.
