I will like to know the type of coil spring I need to replace the broken one in the windows. I am including the windows seal number and windows picture.
Do you have the coil springs in stock, I need about 8 (2 on each window and I have 4 windows spring to replace). Please let me know the cost.
The windows Series is 8500/8501
AAMA/NWWDA 101/1 S.2-79
H - R20 - 48 x 78
H - R30*- 36 x 64
What coil spring do I need?

I'm not able to identify what you have from this information. We will need you to remove one of the coil balance assemblies from the window in its entirety and show me a picture of the part itself. That will allow us to match it up with something in our inventory.

Attached is the picture. One on each side of the window. The physical weight of the window is 19 lbs. After carefully looking at the coil spring, it shows as a single coil that broke into two with each on separate part. What I do not know is the coil spring I need is with one loop or two loops? The first image shows the assembly one on each side. The second image is the complete picture of how is attached.

Thanks! That looks like an older version of our 15-180 pivot shoe. This is compatible with the Series 190 coil spring, 15-186 clip, and 15-182 drum. I am confident that you can use these parts to repair your window.
Since your sash is 19 pounds, I specifically recommend the S190-940 spring. Each spring carries 9 pounds of support, giving you 18 total pounds of support for the whole sash. That should be sufficient in your case. You only need one on each side, regardless of how many you had before (which I think was also just one on each side)
