For a tilt 3/8" tube diameter spiral balance, see our Series 900. The ones you need based on the lengths you have listed here are our S900-29, S900-12, and S900-17. Since none of your balances have color tip bearing included, you will have to weigh your window sashes and refer to the sash weight chart located directly on the store page. This is the only way to determine the correct color tip bearing. Guessing a color tip is not an option, because then you will be risking the chance of ordering the incorrect color tip. |
