I need to replace a window channel balance. It is stamped 44 58.
No other markings. The metal channel without the plastic ends is 44 inches long. There are 4 springs inside, 2 stacks of 2. I believe they are Traco windows.
The cord broke. It looks similar to a 60 series channel balance but I have not seen any with 4 springs inside. They are large, heavy windows.
Any thoughts?
