Hi there! We can definitely help. The best way to identify a coil balance system is to go by the pivot shoe, which acts as a kind of key that lets us know what everything else is. Your pivot shoe looks like our 15-199, which is compatible with our Series 160 coil spring. Note that this spring is 1/2" thick. You'll also need the stamp printed on the old one to confirm the best option. You should be able to reuse your old cover and shoe, assuming they aren't too damaged. They still seem to be in working condition to me but it can't hurt to double check. As for the pivot bar, look at our 26-040. This looks similar to me, but again see what you think. Let me know if you have any questions! |

Thank you! I'm glad you were able to get them out to confirm. So, since they're 3/8" thick, I recommend our Series 165 instead. This is the same as the Series 160 but thinner. Based on your stamp, I'd specifically recommend the S160-5. As for the cover, see our 15-205. This is a triple support cover for the S160-5 and I believe will work well in your window. Finally, concerning the cutout in the window, you may find the video below to be helpful. |

My apologies! If you just need two coils on each side of the sash, then yes, the 15-204 Dual Support would be the better choice. Let me know if you have any other questions. |

Yeah, I thought that might be the case. The reason I recommended the triple cover was because yours looked pretty long; I figured it was too long to be a double. But if you only have two springs on each side, then that's that. You want a double support, not triple. What might have happened is whoever installed these originally only had triple covers on hand and installed them for lack of anything better. It happens all the time. Another way to confirm this is to go by sash weight. If you have two 5 pound springs on each side, then the sash should weigh 20 pounds (5 x 4 = 20). That will decide for you once and for all how many you need. |

As a matter of fact, our video team has been in the process of filming just such a tutorial video. They're nearing completion and expect to have it done sometime next week! You can keep an eye out for it on our YouTube channel here, or you can drop us a line and I can link it to you directly. |
