Product Description
This is a Series 351 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.

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.
