Choosing The Right Roof Box

Everyone has their own preferences regarding choosing the right box for their needs. However, even as you consider your preferences, you still need to select one that meets your needs and your vehicle's specifications. The following are some factors you should consider when selecting a roof rack box.

Factors To Consider When Selecting A Roof Box


Generally, roof rack boxes come in two main dimensions: long boxes and short boxes. A long roof rack box will run the full length of the roof of the vehicle and might even hang over the bonnet for vehicles like trucks and SUVs. These boxes are ideal for carrying long camping gear, canoes, and surfboards.

On the other hand, short boxes are short and only ideal for carrying smaller luggage. They also tend to be cheaper than longer ones.


Always choose a roof rack box that matches the measurements of your vehicle. You want to avoid spending a fortune on a roof rack box only to find that it doesn't fit into your roof. This can make the roof rack box loose and might even expose your luggage to damage and loss when on the road. Remember to go through the legal requirements for the maximum height allowance for highways your car can have in your region so that you can know how big your roof rack box can be.


Before buying a roof rack box, consider the weight limits for your car and your luggage. The weight limits for your roof will help you determine the type of box to get. Generally, the roof box should have a maximum weight capacity that is equal to or slightly lower than the weight limits of the vehicle.

What To Do Before Installation?

Before starting your installation process, always check on the following aspects:

  1. Ensure that your roof and rack are in the best condition for installation. If the roof rack is new, then you will be good to go.
  2. Get the necessary tools and equipment for the process.
  3. Clean the roof rack and the roof and ensure that all the parts are well-oiled to avoid rusting after installation.

The Installation Process

The installation process for roof rack boxes is relatively straightforward. The following steps will guide you in the right direction:

  1. Place the lower leg fittings of the roof box into the gutters on the roof of your vehicle. These fittings hold the roof box in position when fastened on top of the car.
  2. Carry the roof box to the top of the vehicle, ensuring that the lower leg fittings are aligned with the extensions on the roof box. Since the roof rack box might be heavy to carry alone, you can ask a friend or two to help you with this step.
