It could be 16C, to check remove the window sash and place it on a scale.
SWISCO product S800-17 with stamp option 16C will carry a window sash weight range of 12 through 18 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. |
