Starting with your pivot shoe, see if the measurements of our 15-199 match up. This can be used with the Series 165 coil springs. Your coil spring should have some sort of stamped number or marking to tell you which spring strength weight to choose. If it does not, please get back to us with the exact weight of your sash. Lastly, the spring cover will be our 15-205. Review all the replacement parts provided and let us know if any other questions come up. |
