Hello Gary, Take a look at our S900-28 spiral balance. You may need to remove and weigh your sash in order to choose the appropriate tip color. There is a chart on our product page explaining which color you'll need based on your sash weight. Please let us know if you have any other questions or concerns. Thank you. |

For a 20 pound sash, you would need the green tip option on our S900-28 spiral balance. Let me know if you have any more questions. |
