If you cannot locate the stamp number on the original balance please remove the window sash and place it on a scale.
The weight of the window sash is needed to determine the proper stamp option.
Series 380, 31 inch
Stamp Option 3010 will carry a window sash weight range of 7 through 12 pounds
Stamp Option 3020 will carry a window sash weight range of 12 through 16 pounds
Stamp Option 3030 will carry a window sash weight range of 16 through 23 pounds
Stamp Option 3040 will carry a window sash 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.
