Hello, Take a look at our S385-33 channel balance. You'll need to follow the chart under the product description to choose the correct spring tensions based on the weight of your window sash since the (23 9) stamp on your balance is based on an old weight system. Also, confirm that your bottom nylon attachment matches the dimension shown below. Thank you! Alternate view of 15-004
