my window balance has the number 30 3 Caldwell AM printed on it. I am ordering 4 of the 31" series 380, would I need to select the option 3030 for the correct fit?
Thanks for the help,
Tony

Good Afternoon,
Please take a look at the Swisco Series 380-31" Channel Balance with the stamp option 3030. The 3030 stamp will carry an approximate sash weight range of 16 *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. |

The sash is 20 pounds.
