Worked great to attach a roof box someone sold me without the hardware, to the roof of my Honda. Fit perfectly except that I had to drill some extra holes on the box but it had nothing to do with the shape or size of this hardware. Quick and easy to install.. and still holding after a year of use. Well worth what I spent.
