Here's some pics of my install. Its made of aluminum sprayed matte black from an old trailer awning. All bolts and nuts are stainless except for the four OEM bolts that secure the original plastic rack. I can be removed in just a few minutes, but I never have. I have since added a bolt with fender washers and a nylock nut to make sure it can't just pop off. I did loose one once but it was years ago, about 20 degrees out, and I hit a large pot hole at speed. The old latch was plastic, the new ones are usually metal. Thats what broke on mine. MThis set up is pretty robust, you could pretty much drive a car on it. It is made from a large black cutting board from Target. Total cost maybe $12.
