You need to roll the awning completely out and it will be on the tube on the one end. I know this because I just had the awning fabric replaced and when I had some other work done on it, the repairman put the awning out for me and I snapped a picture of the label. I sent that to the awning guy and that was just what he needed. It tells the length, etc. I had previously taped the awning up and didn't think it would unroll, but turned out it did and I was able to get all the info for the repair.
