You may need the 2840 option, weight the window sash to check.
The 2840 will carry a window sash load weight range of 23 through 28 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.

You may need the 2950 stamp option. However, in order to determine the series of the balance, you will need to identify the shoes that are attached.
