Hello! Your pivot shoe looks like a match for our 15-177, which is specifically designed to work with our Series 152 coil spring. Please look these two products over and let me know if you had any questions!

Thank you. For the series 152 coil balance I'm not sure of the sash weight. How can I calculate that? This is a pic of the label on the inside of the window.

The label doesn't tell us anything, unfortunately.

There should be a number printed on the band of the coil spring that will tell you which option to choose. If that number is too faded to read, or missing entirely, then you will have to weigh your sash on a scale.

Once you have that weight, you'll want to divide it by the number of springs that support it and then pick accordingly.

For example, if your sash is 20 pounds and you have two springs per side, then you'd want to pick the 5 pound option (20 divided by 4 is 5). Hopefully that makes sense.
