Hi there, thanks for the inquiry. To start with the keeper, look over our 90-237. For the coil balance system, it appears you have the 15-111 pivot shoe which is compatible with the Series 160 coil balance. You'll need to check the tongue of the coil for a stamped number to determine the correct option. If yours doesn't have a number, just weigh the window sash to see which option your window falls into. Let me know if you need any further clarification. |
