How to measure the length of the Series 751 channel balance.

Product Description

This is a Series 751 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 21" long metal channel.
Comes fully assembled with a 15-014 shoe attached 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.
Used in windows manufactured by Kolbe as well as others.

Stamp Option	Sash Weight Range
20R	10 to 17 lbs
20HD	17 to 20 lbs
20TG	20 to 30 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!

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.
