Hello! This looks like our S395-24 channel balance. We actually just added two new strength options for you, since your original stamp indicates that your sash weighs 34 pounds. You can use either our 2365, which supports 30 through 34 pounds, or the 2370, which supports 34 through 37 pounds. You may want to weigh your sash to confirm that your sash is precisely 34 pounds just to be sure. |
