If you need further help selecting your spiral sash balance:

Step B1 - Top Sash Balances
1. Measure the overall height of the top sash (including horns, if used). This is the Closed ‘C’ Dimension.
2. Refer to appropriate Closed ‘C’ dimensions on size chart and select the Balance Number matching the Closed ‘ C’ Dimension.
3. If there is not an exact match to Closed ‘C’ Dimension go to the next smaller Balance Number
e.g. – For Closed ‘C’ dimension of 341mm select balance number 110.

Step B2 - Bottom Sash Balances
1. Measure the overall window opening height from sill to head. This is the Extended Dimension ‘E’
2. Refer to appropriate Extended Dimensions ‘E’ on size chart and select the Balance Number matching the Extended
‘E’ Dimension.
3. If there is not an exact match to Extended ‘E’ Dimension go to the next larger Balance Number size.
