It features sturdy hidden bracing and coated hardware to prevent rust and keep tubes strong. Built from polished stainless steel or powder-coated steel, the bars can easily be trusted at the time of secure footing. The universal Nerf bars’ 3 inches round designs are frame mounted to offer maximum strength while the 4 inches styles are body/rocker mounted for quick installation.
