looking for window balancing spring

Question

Hello, I'm looking for a replacement part for my window. navigating through your site and I arrived to this one seems very similar to my window part that's broken coil spring. May I get help if this is the right part or if not, what can I get you more information to identify the correct part? Thanks for your help in advance!

Hello there. Good eye. Yes, this is the S140-07 Coil Balance system. It is the same design, and the '7' gives away the spring weight. Let me know if you have other questions!
