Hello,

Many older wood windows use the Series 500 spiral balances. This may work for your application as long as your original balance tubes have a diameter of 5/8".

If so, you'll need to measure the length of your housing tube to choose the correct replacement. From there, you'll follow the chart under the product description that shows the sash weight ranges supported by each color option. We also offer the 17-012 sash brackets for installation, as well as the 75-005 charging tool. Take a look and let us know if you have any other questions.
