Hello, Julie. The part in question is called a coil balance. Yours in particular is a match for our Series 190. You may also need a new 15-186 clip, if your original is too damaged to reuse. |

Hey, Julie. There should be a number printed on the spring itself, near the screw hole. If there isn't, then I'll have to know the exact weight of the sash instead. I can use that to calculate the proper option. |

Yes, the spring in this case is the coil balance. I'm sorry for using an unfamiliar term, it's just some shorthand I use without thinking. If all you need is the clip, then you can use the 15-186 I mentioned above. We also sell the 15-182 bushing, in case that's also missing. If you did need new coil balances, then you should definitely remove them ahead of time to see if they have a stamp. Otherwise, you will need to remove the sash from the window and place it on a scale to get its weight. Any common bathroom scale will do, but it has to be precise. As for removing the coil balance, the video below may be helpful. It's a pretty easy project, to be honest. Using a handy person to do it for you may cost you more money than it's worth. |
