Hello there! I recommend you take a look at the 15-259 pivot shoe along with the Series 159 coil springs. The video below will go over the details regarding the replacement process. Let us know if you have any questions! |

I'm afraid these stamps don't tell us what weights you'd need. If you can get back to us with the precise weight of the sash, we can calculate the spring weights from there. |
