Product Description
Series 850 replacement 30.5" block and tackle rod balance system for a tilt window, often used by Barrier and other window manufactures. Sold individually.
Shoe Option Sash Weight Range

white 1 1/4" 22 to 28 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.

Limited Supply, sold while supplies last. Please contact us for help with a substitute if needed.
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 color options represent different strengths. Choose the color that best resembles the color of the shoe of the balances you are replacing. If you do not see your color available in 'options' or you are unsure of which color to choose: ask our experts for help.
