Hello from SWISCO! The nylon fitting looks like our 15-102 double side load carrier that holds two Series 145 coil springs. If the nylon fitting is not broken just replace the broken springs. You will need the spring weight number stamped on the old spring when ordering. Hope this helps! |

Absolutely. Weigh the sash and divide the weight by the number of coils. That will tell you how many pounds per coil you need. Then, you can choose a coil stamp that is close to (or the same as) the pounds-per-coil number. If you get funny results or become confused, send the weight to me. |
