Ballast for window?

Hello there!

Thanks for reaching out to us. It sounds like you're looking to replace the pivot shoe but I'm afraid yours is too damaged to identify. Would it be possible for us to see a photo of an undamaged version? Seeing the pivot bar that goes into this shoe would be a great help as well. 

Thank you kindly! If this is a CertainTeed brand window, see the 15-192 that is designed to use the Series 170 and Series 171 coil springs. You can reuse the old springs if they're in good shape. 

If you have a Simonton brand window, I would recommend the 15-259 pivot shoe and Series 159 coil springs. I know it doesn't look the same as your old shoe but it's our best option. The video below will go over the process along with additional needed parts. 

Let me know if you have any questions!
