Product Description
Series 500 spiral tube sash balance with cross piece for a non-tilt window. The tube measures 31" in length with an internal rod that measures 31-1/2" in length. The tube diameter will actually measure 9/16" but it is considered 5/8" in the trade. Spiral window balances come fully lubricated and ready to be charged.
Color Tip Sash Weight Range
Red 7 to 29 lbs
Blue 12 to 31 lbs
Black 31 to 40 lbs
*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.
Good Idea!
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.
Helpful Tip!
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.
