Hi there! This sticker doesn't tell us what hardware your window uses, I'm afraid. The best and only way for us to ID your hardware is to see it removed from the window to compare to our inventory. It sounds like you may need a new coil balance so if that's the case, we'd need to see an undamaged pivot shoe removed from the track. If we can identify that, it will tell us what coil springs you'll need. Thank you! |

Thanks for the additional pictures! Your hardware looks like a good match for our 15-177 that's designed to use the Series 152 coil springs. There should be a stamped number on the band of the spring that will indicate what coil weight to choose. Look this part over and let me know if you had any questions. |

Sure, you can weigh your sash on a scale. If you can tell me the precise weight of your sash along with the total number of coils in the window, I can work out what you need from there. |

My pleasure! Thanks for confirming that for me. With a sash weight of 18 pounds, you can use (1) S152-9 9 pound spring on each side of the window which totals 18 pounds of overall support. |

You got it! |

No need to apologize; we're here to help! You can actually go with either a 7 or 8 pound spring. Either will be okay as long as the coil weights are within a pound of your sash's actual weight. The decision is ultimately yours! |
