Thanks for posting, Gail. I agree, it sounds like you might be looking at our S900-19. Our balances can indeed replace those with a plastic casing.
I'm not sure about the tip, though. I'd have to know what your sash weight is to confirm. The Blue Tip can carry a window sash weight range of 9 through 21 pounds, while the Red Tip can carry 6 through 16 pounds. Which weight range would be better suited for your sash? Please keep in mind that the weight range 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. |
