Roof racks are structures installed on the roof of a vehicle to carry additional cargo such as luggage, sports equipment, bicycles, kayaks, or skis. They consist of a base rack, which attaches to the roof of the vehicle, and various accessories, such as cargo boxes, bike racks, or kayak carriers, that attach to the base rack. Roof racks can be made of various materials, such as steel, aluminum, or composite materials, and can be designed to fit a wide range of vehicle types and models.
