Hello ? I have identified replacement housings (15-086) by dimensions and appearance, and the coils by rating and dimensions (S180-6, S180-7) but cannot find a match for the pivot housing. Please see the attached photos. Will the 15-087 replace both the lower tandem housing and the pivot housing, or do you have a direct replacement for the separate pivot housing component?

You have an older coil balance system that is unfortunately not made anymore. That said, I believe that you can use the 15-087 coil spring pivot with the 15-086 tandem housing. You won't need two tandem housings like your set up, either, you can just install the S180-7 spring directly in the 15-087 pivot carrier and S180-6 in 15-086.

Thanks Paul! I took a chance and purchased the parts. However, I cannot figure out how to attach the tandem coils to the bracket. Any suggestions?

It can be a little tricky, since the window track offers such little room to work with. But basically the two holes on the Series 180 hook onto the bracket (usually something like our 16-024, which should be like what you have in your window now), which is mounted near the top of the track. The diagram below will hopefully illustrate what I mean.

That's awesome! I'm so happy this new system worked out for you. Please let me know if you ever needed anything in the future.
