*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.
Balances are sold individually, however, it is a good idea to replace both window balances at the same time. Pairing a new balance with an old one would cause the new balance to wear out faster.
You should choose the color tip that matches the color tip of the balances you are replacing. If you do not see the tip color available in 'options' or you are unsure of which color to choose: ask our experts for help.
