Rock solid. Perfect height for my awning. I got a no-name 270 awning off of Amazon. Much to my surprise, it came with mounting brackets. I had already ordered these brackets, assuming that my Amazon awning would not... and I'm glad I did. These bolt right up to my Datin canvas cage, and they're the perfect height to allow unobstructed access to my Chevy Colorado. I love that they are designed to work with my rack and the fact that these things are bomb proof, just like the rack. Very happy with the purchase, even if they are quite expensive.
