Nerf bars are installed by hand, with the hardware and tools provided out of the box. For example, APS 3" round nerf bars for the Honda Ridgeline can be installed by simply screwing the mounting brackets onto the nerf bar, then aligning the brackets to the body of the SUV and then screwing the bolts on.
