Thanks for posting. Please take a look at our S500-19 spiral balance. Does that look about right? You may also want to consider a bracket similar to our 17-012.
As for the color of the tip, you will have to weigh your sash and compare it to the ranges available for the S500-19. Its Red Tip can carry a window sash weight range of 6 through 19 pounds, while the Blue Tip can carry 10 through 29 pounds. Does your sash's weight fall within either of these ranges? 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. |
