Thank you for reaching out to us. I recognize what you have here. We don't have an exact match for this but our 15-259 shoe and Series 159 coil springs are my picks. Our video below will detail the replacement process as well as the additional parts you will need. |

That depends on the weight of the window sash. If you can get back to me with the exact weight, I can calculate what you would need from there. |

Thanks for getting back to us! We recommend using (1) S159-7 7.5-pound spring on each side of the window. This totals 15 pounds of overall support and should work for you so long as the spring weights are within a pound of the sash's actual weight. You will also need the 15-255 coil support since you're using one coil spring per side. |
