Hi,
For the 22" Series 500 balance you could use a Red Tip or Blue Tip to accommodate a 12 pound sash. We recommend matching up to the original color tip if possible. 22" Series 500 balance weight ranges: Red Tip will carry a window sash weight range of 6 through and including 19 pounds. Blue Tip will carry a window sash weight range of 10 through and including 29 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. |
