Rhino-Rack is a highly-regarded designer and manufacturer of vehicle load carrying solutions. Established in 1992, the company engineered and sold its first lightweight, heavy-duty roof rack system in Haberfield, New South Wales, Australia.

Thanks to the demands of the Australian Outback, Rhino-Rack took advantage of their outdoors' unpredictable nature to create the most efficient roof rack systems and hauling accessories that are more than capable of overcoming extreme temperatures and difficult jobs. From the Vortex Crossbars to the Pioneer Platforms, Rhino-Rack Roof Rack Systems have consistently evolved with time.

Whether you're into cycling, kayaking, surfing, or someone who's just looking to keep their vehicle interiors clean, Rhino-Rack's massive selection of carriers makes it easy and quick to safely transport gear from place-to-place. Ranging from roof rack awnings to cargo boxes to alloy trays, Rhino-Rack Carriers guarantee a precise solution on various work and play applications.
