I need several replacement coils for double hung windows. The panel dimensions are 33.25 X 35.5", double insulated. The actual weight of each panel is 30 pounds. I have 16 windows that need replacement. The old coils were 5 pounds each, with four on each window. Several of the windows currently fall as if nothing is even slowing them down, others fall a little more slowly. I have attached an image of an old coil. Please let me know what I need with pricing (I am assuming 7 lb. coils, with four on each window, for sixteen windows).

What is the difference between the 190 and 152 series coils, and why would I choose one over the other?

Based on your picture, your coil balance matches our 190 Series. We highly recommend that you replace your hardware with something identical or very similar. The preferred shoe for the Series 190 is the 15-180.
If you you are still unsure, you may submit additional pictures of your balance and shoe from different angles so that we can determine other options.
