What part is this and how do I replace it




Hi there!
The part in your pictures is called a coil balance assembly. We can definitely help but we'll need to see a picture of your pivot shoe removed from the window, along with dimensions, to compare to our inventory. If we can ID the pivot shoe, that will tell us the coils and accessories that you’ll need. I'll also post a few videos below that you may find helpful.
Let me know if you have any questions!




Thanks for the additional pictures! You have an old Simonton balance that isn't made anymore but take a look at the video below where we walk you through the entire replacement process, along with the other parts that you'll need for this repair.




Sure, it looks like you have a double coil support but please correct me if I'm wrong. If that's the case, see the 15-256.




If you watch the video I linked you to previously, you'll see all the parts we recommend for the 15-259 conversion which is designed to work with the Series 159 coil springs.
