Broken window coil spring

Question

Window is 26" tall and 28.5" wide, double pane.  I don't see a manufacturer name.  Coil springs are broken (left and right).  On the spring there is a 9 with a J below it.  Attached pics will describe the rest better than I can.

Hello, thank you for posting,

We do not carry this exact balance assembly, but we recommend reviewing the dimensions of the 15-177 pivot shoe as a replacement option. This shoe is compatible with the Series 152 coil springs.

Based on the 9 stamped on the original spring, you should be able to use (1) S152-9 on each side of the window. This spring can support a 9 pounds of support. Together with the other side, the total sash weight should be 18 pounds. I recommend weighing the sash to confirm this!

Also review the 15-143 coil bushing, 15-144 bushing cap and 15-145 barrel for a new cover support.

Let us know what you think and if you have any additional questions!
