Thanks for posting. Please see our 15-177 pivot shoe and Series 152 coil spring. These appear to match what you had originally. You will need the number printed on your old coil spring to confirm the best Series 152 option.

I believe you can use our 15-144. These stack on top of each other, just like the coil springs.
Since you do not have a number on your old spring, we'll need to know the weight of your sash and exactly how many springs are used on each side of the sash. |

I'm afraid we don't have a coil support like the one you have in your picture. At least, not one that can work with the hardware I mentioned above.
If your sash is 20 pounds, and you use four springs per sash, you would just divide that among the springs. In your case, you'd want four S152-5 coils, each of which can carry 5 pounds. |
