Coil balance replacement/pivot bar replacement.

Hello there. This is a Simonton Coil Balance system that is no longer made, but the Series 159 Coil Balance springs and 15-259 Pivot Shoe can replace it. The video below shows how to do this, and also explains the other hardware you need. Let us know if you have questions.

The 15-259 Pivot Shoe, Series 159 Coil Balance springs, 26-083 Pivot Bars and all else listed in the video I posted above are sold separately. For the spring weights, give me the exact weight of your window sash. I can calculate what you need.

If the sash weighs exactly in the range of '16.6-17' pounds, then use the S159-08 8.5 pound spring, one on each side of the sash. That will give you 17 pounds of total support, close enough to the exact weight. As for the coil covers, as the video I posted above shows, you can use the 15-255 single supports.

It's more important to match the sash weight, with half that weight on both sides of the sash (so, for instance, a 16 pound sash having 8 pounds of support on both sides), rather than matching the exact quantity of coil springs that you previously had. All that matters is hitting that proper support weight. Let us know if you have further questions!
