The Series 900 spiral balance and our 15-187 shoe do not go together. Could I see a few pictures of your pivot shoe? I will also need to know its thickness and width. Those are the two most important dimensions. Thanks!

Ah, I see. Looks like you have a Thermal Guard window. This old pivot shoe has been improved, and newer models use our 15-070. Check that out and see what you think.
I'm actually surprised they used an S900-22" balance. Are all the windows you have using 3/8" balances? Also, what is the color of the nylon bearing at the end of the tube? |

Best way to determine that is to measure the diameter of the outer metal tube. If it is 3/8", then you have our Series 900 spiral balance. If it is 5/8" or 9/16", it is our Series 600 instead.
