The awning are pretty generic. You have two main choices for brands. Domestic and carefree of colorado. I feel the carefree is a better overall awning but you can check out both.
They will both be called Bag awnings for pop ups. So called because they roll up into a bag. The unit slides into your awning rail that is mounted on your roof line. if you do not have one, then you will need to install one. It is simply screwed to the side wall at the roof line.
They well them by the foot so you get a 9' awning for a 10' box.
