Product Description
This is a Series 500 spiral balance, a popular balance that is used in both wood and aluminum non-tilt windows. It moderates the operation of your window sash to allow the window to stay open when raised.
  • This balance has a 23 long metal tube with an internal rod that measures 23-1/2" in length.
  • The strength you need should be indicated as a color tip at the end of your old metal tube. If you do not see a color tip weigh your sash on a scale and refer to the chart below.
  • The tube measures 9/16" in diameter but it is considered 5/8" in the trade and houses an internal spiral rod with cross-piece.
  • Can work for either the left or right side of the window interchangeably.
  • 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
    *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.
