If you originally had black tip 30" Series 500 balances you should replace to just that; I have added the Black Tip option for you, here is a product code link to get you started: S500-30
The 30" Series 500 Balance with Black Tip option will carry a window sash weight range of 31 through 40 pounds. This information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |
