- This balance is ordered based on tube length and sash weight. When taking measurements, measure only the metal tube. If the balance is not available, measure the height of the visible glass. This will be your tube length. Then remove and weigh your window sash on a bathroom scale to get the sash weight and determine the coupling color. These measurements are crucial to the performance of the balance. Check out our guide on measuring spiral window balances for more info on how to measure your balances properly.
- Weight capacities are listed per pair of balances in pounds.
- For optimal performance, we recommend replacing both balances at the same time.
This balance will need to be tensioned using the Spirex and Spiro-mite Tensioning Tool
