Review on Universal Side Rail Mounted Roof Bar - Apex RB-1006-49, Black by Marcus Curry

So after reading the reviews, I thought, how loud could these possibly be? OMG! 45mph and it was incredible! Howling harmonics! It's caused by the adjusting track underneath. It does not go the entire bar length, just a couple inches either side of the mount. A little strip if gorilla tape completely solved the issue. The manufacturer should include a plastic trim piece for the gap. Otherwise, this seems to be a good quality product and very easy to install. I'll be using it to hold a large solar panel while camping. Perfect for my use. In spite of the HOWL, I would recommend this product.
