Prism tilt window Spring 35"

Question

Hi, I am looking for these springs(?), that go inside the tracks on a Prism tilt-window. I believe they may have snapped and come out of the holder on top. The window will go up and down with no problem, but without these installed it will not stay raised.
Thank you for any help you can offer.

Thank you for posting. I recommend looking at our 15-199 pivot shoe and confirming that the dimensions match. If so, you should also consider our Series 160 coil spring. Let me know what you think.
