Hello,

Your photos resemble our 15-199 balance shoe, which is used with the Series 152 coil springs. Take a look and see how the dimensions compare to yours. To determine the spring strength for your coils, you'll either need to local the stamp on your existing coils and choose the corresponding option or weigh the window sash and divide the weight by the number of coils in the window. Thank you!
