The combination of nylon and steel shoe would be our 15-040 . For your 18" balance tube, we'll need to know how far the spiral extends from the tube when fully retracted to give you the correct balance series. Thank you! |

I'm sorry for the confusion, but we need you to put the spiral into the tube as far as it can go and measure how far it sticks out, which should only be a few inches. |

Thank you for confirming! It looks like you will need our Series 500 -18 balance with the red nylon bearing to go with the 15-040 balance attachment. Please let us know if you have any other questions! |
