Single Coil broken

Question

Hello;
I am trying to identify replacement parts for the coil and lock shoe (for double tilt window) that are broken on both sides of the lower window. I cannot identify the stamp on the broken coil, but the window weight is aprox. 15 lbs. Based on the previous posts and looking at your parts, I have identified the following replacement parts (as it seems that you do not carry the exact same lock + coil system that is broken): 15-191 (shoe), 160-9 (coil), 15-150S (cover), 15-148 bumper.
Could you please let me know if this is correct or if you would suggest other parts. The broken coil is 1/2 inch, the plastic cover is 1 1/4 inch.
Thank you!

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.
