I had my awning replaced in 2014 May due to wind blew up the old one.
When they replaced it, they did not put the guard on it and now it is trying to mold underneath on the first flap when it rolls out.
I just emailed Camping World (who installed it) as to why the guard was not installed on this new one, still haven't heard...
But this video will show you the actual guard, I think it is metal, and that's probably the price difference Larry, just guessing though...
Hope this helps...
