Thanks so much for contacting us. To better help us determine what you need, can you please send us a photo of your pivot shoe?

Perfect, thank you! That looks like our 15-180 pivot shoe, which is meant to be used with our Series 190 coil spring. You will need the number off the old spring to determine the best Series 190 option.

I believe that is actually a 9, based on the orientation of your spring. I'm afraid we don't have balances that can go up that high. Can you confirm the weight of your sash? We may be able to distribute the weight among more weaker springs. Let me know!
