Roof Rack
It is a device installed on the roof of a car to increase the cargo space of the vehicle, making it easier for car owners to carry large items such as skis, surfboards, bicycles, camping equipment, etc. It provides more convenience for travel and is especially suitable for travel enthusiasts and outdoor sports enthusiasts.
Â
Cargo function
The main function of a roof rack is to increase the vehicle's cargo capacity. It can carry items of various shapes and sizes, and can be securely secured using accessories such as straps, a luggage net, or a dedicated luggage frame. For example, when camping, tents, sleeping bags, tables, chairs, and other equipment can be placed on the roof rack to free up more space in the vehicle for passengers.
Â
Multifunctional expansion
In addition to the basic cargo function, the roof rack can also serve as a base for installing other accessories. For example, you can install a roof luggage box to store items that need to be waterproof and dustproof; you can also install a bicycle rack to facilitate carrying bicycles for cycling activities; you can also install a ski rack, a surfboard rack, etc. to meet the needs of different outdoor sports.
