This balance is from a jeld-wen window. The only number I can find on the balance is 5737877 (?) I took a photo of it.
The only number I can find on the window is JW-14 8/29/00 B#1. As you can see in the photo the balance measures 28 1/2 inches long.
I appreciate your help with this as I have been dealing with Jeld-wen since February.
