Hi, several of my windows do not stay up and I cannot find any markings on the existing ones. I have attached 2 pics of what is in the tracks. There is one on each side of the window. Please help me in what I need and how to replace them.
thank you

Hi there!

Thank you for reaching out to us. We're happy to look into this. Can you show us a photo of the pivot shoe? Once we ID that, we can determine the compatible coil balances.

Thank you, Vic. Your pivot shoe matches the 15-111, which is used with the 1/2" Series 160 coil springs. The video below will go over how to determine the coil spring weights.

Please let me know if you have any questions.
