Thanks for writing in your question. Let's start with your coil balance accessories. I placed a list of those replacement pieces you will need on this page. Look over each one and let us know if you have any questions about them. As for the coil springs, these pieces are used with the Series 190 springs. It appears you will need two. In order to provide the exact part, we will need to know the stamping information on your current coils. If there aren't any stampings on your coil, you will have to provide us with the weight of your sash. |
