Hello there. All of our parts you referenced in your inquiry needed to replace your coil balance system are correct, with the exception of one. Since your window sash weighs 15 pounds, the S160-7 coil spring would make a better choice in this case. I have placed all the parts discussed in a list on this page for you to review once more in case you should have any further questions for us. |
