If the outer nylon tube of your balance is 3/8" in diameter, then you can use our Series 900 as a replacement. |

You can order the S900-30 right through its shop page. Note that for a white tip balance, you'll need to obtain the exact weight of the window sash. You can then match that exact weight with one of the weight ranges listed alongside each color tip option under the balance's product description. |
