Thanks for posting! Based on your photos and measurements, the balance you need is the S385-28. Since yours is stamped with a 27 4 you'll likely need the 2740 stamp option. Although, you may want to double check that the weight of your sash falls between 19 to 26lbs. Please let me know if you have any questions. |
