    The dimensions of a car roof box affect its compatibility with the vehicle and its aerodynamics. The dimensions include length, width, and height. Longer roof boxes offer more storage space, but they also affect the car's aerodynamics and are more difficult to fit. The height of the roof box should also be considered. A taller roof box will affect the car's clearance height, making it difficult to drive in some areas.

  • Material

    The material of a car roof box affects its weight, durability, and weather resistance. Common materials used to make roof boxes are ABS plastic and fiberglass. ABS plastic is preferred because it is lightweight and affordable. Fiberglass is more durable than ABS plastic but heavier.

  • Security Features

    Security features prevent theft and unauthorized access to the items stored in the roof box. Car roof boxes come with lock systems and handles. The lock systems secure the roof box to the car. Handles provide access to the items inside the roof box.

  • Installation System

    The installation system of a car roof box determines how easy it will be to install the box. A car roof box comes with mounting brackets, clamps, and an adjustable U-bar. The adjustable U-bar and mounting brackets secure the roof box to the roof rails of a car. Clamps secure the roof box to the roof of the car. Roof boxes with an easy installation system are easy to install and remove.

Proper maintenance of a car roof box is important to enhance its durability and performance. Here are some maintenance tips:

  • 1. Cleaning: Regular cleaning of the roof box is important to maintain its appearance. The dirt and grime stuck on the roof box affect its appearance and performance. To clean the roof box, use a damp cloth and mild soap.
  • 2. Lubrication: The moving parts of the roof box, such as the locks and hinges, should be lubricated regularly. Lubrication reduces friction and prevents wear and tear. Use a silicone spray to lubricate the moving parts of the roof box.
  • 3. Inspection: Regular inspection of the roof box is important to identify any damage or wear. Inspect the mounting system, locks, and hinges of the roof box. In case of damage, replace the parts.
