These brackets let you mount your James Baroud or Autohome tents with the proper lateral support, even if your rack is narrower or wider than your tent base. When fitting a James Baroud or Autohome tent to a rack that is smaller (narrower, shorter or both) than your tent base footprint, the included spacer raises the mounting height of the tent so it rests on the edge of the racks side profiles for full support. When mounted to a rack that is larger (longer and wider) than your tent base footprint, the brackets position your tent flush on the rack for full support and use of the included spacer isnt required. These brackets make sure your tent is positioned for maximum support so you can rest easy. Works with both Front Runner roof racks and Front Runner load bars. Supplied with all installation hardware and fitting instructions.
