Resending request with photos.
I have a failed channel balance on a Pella single hung window. I need the channel balance and metal pieces that connect to the side of the window. I have 3 windows and should replace all 6 channel balances given this one failed.
The measurement of the metal section is 20.5". My guess is it is 21" given the bottom plastic piece is longer than the replacement versions on your website. The part is stamped with 2040.
Thanks for your help!
Mike
