Your pivot shoe appears to be a match for our 15-087, which is compatible with our Series 180 coil spring. Look these over and let me know if you agree. You'll need the stamp off the old coil to confirm the best replacement. |

Hello! That looks like our 16-024 mounting bracket. This is sold separately. You can install it using a screw like our 33-072, or just reuse the screw you have now. If your window jamb doesn't have a cut out already, then you can make your own. That is a much less expensive method. I will share a video at the end of this post that shows you exactly how you can do that. Finally, concerning weight, referring to the stamp on the spring is the best method. If you want to know that before you remove your balances, you will have to weigh your sash on a scale and divide that by how many springs are used to support it. So, let's say for example that your sash weighs 12 pounds and you use only one spring on each side, for a total of two springs. You would divide 12 by 2, giving you 6. In that scenario, I would recommend the S180-6, which carries 6 pounds per spring. Here's the video I mentioned: |
