Hello, Jason. I don't think the Series 140 will work for you. Instead, see our 15-180 pivot shoe, Series 190 spring, 15-182 bushing, and 15-181 double spring clip. These parts should work perfectly well for your window. |

We don't have a video on these specific parts, unfortunately, but we do have a cover-all balance video that may be of help to you. I will share it at the end of this post. Concerning how many springs you need, your specific type of balance can only accommodate two springs. It's not physically possible to use any more than that. It may look like you have three springs now, but I think that's just because one of your coils became unwound. You should triple check to be 100% sure. I suppose it's possible that whoever installed these used three springs instead of two, but if that were the case then that means whoever did the job made a mistake. You need to be 100% sure. There should be numbers printed on your old spring that will tell you which option to buy. You need to remove the old springs to read that stamp. |

Hi, Jason! One spring being 5 and the other being a 6 is pretty normal. That means one supports 5 pounds and the other supports 6 pounds, for a total of 22 pounds of support when you account for all four springs. You said before that your sash was only 20 pounds, but you may want to double check just to be 100% sure. If you want to stick with what you have now, you can use the S190-640 (6 pounds) and S190-540 (5 pounds). If you want to change to 20 pounds of support instead of 22, then you can just use four S190-540 springs. Also, I totally forgot to post that video I mentioned. Sorry about that! I'll share it now. |

Hey, Jason. I'm surprised to hear that. I've never heard of a skinny version of the 15-180. Even the older styles, which looked a little different, were all the same size. Up until now, this is the only size I've seen made in this design. Can you confirm the exact size of your old pivot shoe? Seeing a photo of the old and new shoe side-by-side would also be a big help. |

Thank you. This is definitely a new one to me. Can you give me the precise thickness of your original shoe? |
