Hi, Andrew. The pivot shoe in your pictures looks like our 15-087, which is compatible with the Series 180 springs, but you'll notice that the style of our cam is different from yours. Would it be possible for us to see your pivot bar removed from the sash? That will help me confirm if our part will work for you. You can also reuse your original brackets if they're in working order. Have you ever had difficulty opening or closing this window? Your coil weights appear to be calibrated for a sash weighing 16 pounds which would be too strong since your sash weighs 12 pounds. With a sash weight of 12 pounds, you'd want to use (1) S180-6 6 pound spring on each side of the window. As for creating the cut out, you can indeed follow the process we show in the "How to Replace a Triple Coil Balance System" video. We also have another video on this method which I will post below. |
