Length of Series 795?

A home owner says:
Hello,

The balance I need is a plain channel block and tackle for a tilt in window.
I'm pretty sure I need a 795 channel balance. I'm not sure about the length. depending on how I measure it it could be 20-22 inches. The stamp on the balance is 20 9BSI. I think that means that I need a 20in balance, but I'm not sure.

Thanks,
Roy

Thanks for posting, Roy. The only way to measure the length of this kind of balance is by measuring the metal channel alone. How long is that?
A home owner says:
The metal channel alone is 21 inches.

Great. If you have the Series 795 then I recommend our S795-21. The only thing left to determine is the stamp option, which indicates the strength of the spring. We have a chart on the S795-21 store page that lists each option and how much weight they can support. All you need to do is weigh your sash on a scale and cross-reference the weigh to this chart.

My balance is not a 795. Your 795 balance looks just like my balance. Does the stamp on my balance 20 9BSI mean anything to you? My window sash weighs 30lb. Its a large window 51" X 48". (Whole window)

The stamp only tells us how strong the spring is. The only way we can know for sure what Series you have is if you send us more detailed pictures. We need to clearly see the bottom of the balance (specifically, the shoe) and the top clip, so we can see how it attaches to the frame.
A quick learner says:
I am confident that the 795 is the correct one. So I would need a 21" 795 code E S795-21E?

Thanks for clarifying! We were just a little confused as to what Series you had. You said in your prior post that it was not a Series 795. However if you are now sure that it is, then a stamp option of 21E will not work for you. As you can see on the chart, it can only hold 21 through 26 pounds. Your balance will have to be custom made with a 26F option, which can carry 26 through 30 pounds. If you are certain that you have a Series 795, this can be easily done.

Check out this Custom Channel Balance Request Form I've started for you based on your specifications and fill out the blank fields. One of our representatives will get back to you with a price quote and an item to add to your cart.

I received the new window balance. The install was very easy! The window works beautifully! Thank you you for all of your help.
