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?
The metal channel alone is 21 inches.
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.
I am confident that the 795 is the correct one. So I would need a 21" 795 code E S795-21E?
I received the new window balance. The install was very easy! The window works beautifully! Thank you you for all of your help.
