Hello, my entire house is populated with single hanging windows dated around 1992 which say "Philips" on them. Many are very difficult to open and close so I need to replace the channel balances on a bunch of them.
They vary in length...most are either ~ 22 inches or ~ 27 inches long.
The windows vary in size (width), so my concern is about making sure the balance is correct for the weight of the windows.
Any suggestions would be helpful.

Hello. I understand your concerns but, first and foremost, we need to determine what the correct replacement balance would be before worrying about the size and strength. To do that, we'll need to see an undamaged balance removed from the window, including both the top and bottom attachments.
From there, you'll need to collect the lengths and stamp numbers from the metal channels of the balances from each size window. Thank you!

I agree that you have either the S380 or S385 channel balances. Measure your bottom attachment following the diagram below to choose between the two.Once you've chosen the correct series, choose your lengths for each window and the spring strength options based on the stamps printed on the original balances. Thank you!

Thanks -- I am uploading some photos.
A typical balance says something like "19 5 Caldwell CM" on it but many are difficult to read.
Other info I've researched:
I have 5 different window sizes I am trying to match (3 windows with channel lengths 20" and 2 windows with channel lengths 26").
20" channel: the window sashes weigh 12.4, 14.2, and 19 lbs for the 3 sizes.
26" channel: the window sashes weigh 17.9 and 23.7 lbs for the 2 sizes.
Both the width and depth of the channel measures around 15 mm which converts to just over 9/16" (so, I think I need the nominal 1/2" size). I am thinking S380 or S385 series?
What are suggested next steps?
Thanks!
