See our S751-33 Ribbed Tilt Channel Balance. You'll need to choose a stamp option, though your stamp code isn't quite like any of ours. You might be able to use 32R, which is for a sash that weighs  15 through 24 lbs. But if in doubt, obtain the exact weight of your window sash.

Thank you for your response. The actual weight of the sash is 26.3 pounds. Would you recommend the S751-33HD?

Thanks for telling me this detail. If the sash weighs just over 26 lbs, then yes, a stamp option of 32HD, which supports a sash that weighs 24 through 29 lbs, makes more sense. Let me know if you have further questions.
