Product Description
This is a Series 710 channel balance for non-tilt windows. It moderates the operation of your window sash using a specifically calibrated spring and pulley system that allows the window to stay open when raised.
- This balance has a 14" long metal channel. When determining the length, do not include the attached fittings. Only measure the metal channel.
- Comes fully assembled with the 19-009 top and 15-003 bottom fittings and will be ready to install out of the box.
- The strength you need should be indicated as a stamp or imprint on your old metal channel. If you do not have a stamp, or cannot match it up to our options, weigh your sash on a scale and refer to the chart below.
- The width of the metal channel measures 9/16" but is considered 1/2" in the trade.
- Can work for either the left or right side of the window interchangeably.
- Used in Acorn 3500 Series single-hung windows.

*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!
The stamp option is a code that indicates how much weight a pair of balances can support. You can use the stamp on your original channel balance as a reference in most cases, or you can weigh your sash and refer to the chart above. If your sash€™s weight falls outside the weight ranges listed on that chart, or you are still unsure how to proceed,
ask our experts for help.
