What is the weight capacity for the Series 206 balance with a 20 inch tube length?

The S206-20 will carry a window sash weight range of 6 through 19 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.
