Product Description

This is a Series 770 channel balance for tilt-in 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 23" long metal channel.
Comes fully assembled with a 19-036 top mount screw support and a 15-043 terminal clip attached at the bottom and will be ready to install out of the box.
The width of the metal channel measures 9/16".
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.
Can work for either the left or right side of the window interchangeably.

Stamp Option	Sash Weight Range
23A	5 to 10 lbs
23B	10 to 16 lbs
23C	16 to 21 lbs
23D	21 to 24 lbs
23E	24 to 27 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.

Helpful Tip!

This part does not include new fasteners. Do not throw away your original screws, you will need them for the installation of your new part.

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.
