My Channel Balance has "28-3 IS5 CMC43" printed on it. The metal part of it (not including the plastic feet?) seems to be just about 29 inches. I believe it is 1/2" wide (assuming this actually means it is around 9/16" wide, as it is definitely slightly over 1/2 an inch)
I also need to get new takeout clips which I think are of the narrow variety. Also, a piece of plastic covering on the top of one side of my windows popped off as I was trying to reinstall the channel balance--it looks like it would normally cover the top right and left corners of the windows and affix to a screw that is an inch or so below the top of the channel (down the side of the window) Is this something I could find a replacement for on Swisco as well?
