Thank you for sharing your photos with us. Have a closer look into our S380-31 channel balance. This comes assembled with a 19-005 balance top and 15-005 bottom balance shoe. We recommend you reviewing our measurements to see if they align up with yours. If this is correct, then you can go with the 3040 option that holds a sash weight of 23-28 pounds. |
