Hello.
I need help figuring out which parts and correct coil balance weight for my window. The metal coil has the number 540 stamped on it. I hope that helps.
Thank you very much!
Allison

Thanks for posting. I've made a list of replacement parts for you on the right side of this page. I think you'll find they match what you have quite closely.
