Thanks for posting. I'm afraid I don't know what you mean by channel; could you clarify? If you mean channel balances, your window is not designed to work with them, and you cannot use them. Your window has coil balances--our Series 180 coil springs with the 15-087 Pivot Shoe. We can replace these, if needed. Let us know. |

We understand. We are happy to help, we just need a little help from you. On the current coil, there is usually a stamped number or marking on it. You will need to provide us with that information. If there should not be any type of stamping, then you will need to weigh your sash and get back to us with the weight number. This will help us be able to provide you with the exact part number we believe you will need. |

We're getting there. The Patent number unfortunately isn't helpful. The stamped numbers we're looking for will be on the actual Series 180 coil springs inside the 15-087 Coil Housing Pivot or the 15-086 Tandem Coil Housing stacked on top of the bottom pivot. You will need to remove the housings and the coil springs to see this. If the Series 180 springs do not have stamped numbers on them, you will need to weigh both window sashes. Let us know the precise weight of each sash, and we'll work out what you need. If you need help removing the components, see the video below. |

OK, based on those '5' stamps those should be our S180-5, which are coil springs meant to support 5 lbs apiece. Basically, the total amount of coil spring weights must support the total weight of the window sash; they also be even on either side of the window sash. So for instance, if one of your window sashes weighed 20 lbs, you'd want (2) of the S180-5 on either side of the sash. You'll want to obtain the rest of the stamp numbers on your coil springs to make sure you have the right spring weights; or, weigh your window sashes so we can calculate the exact combination you need. |
