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. |

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. |
