MaloneMalone Auto Racks AirFlow2 Alum Aero Cross Rail System, 65in, MPG217

Does it fit to an GMC ACADIA DENALI 2017? The meassure of the bars are about 39.5 inches in the inner distance, the outter distance are about 43 inche

What are the dimensions of the bars? I'm looking for the cross-section height and width. Thank you!

Where are these roof racks made? In what country?

Will these support a 150# roof top tent with a person inside? (if you "don't know", no need to respond)
