These older spiral balances can be replaced by our Series 500, along with a 17-012 bracket that screws to the bottom of the sash. It looks like from your photos you'd need the S500-23 specifically, but double-check your dimensions to be safe. |

My pleasure. Let us know how you make out, and good luck with the repair. |
