Despite being huge, it is very user-friendly and straightforward to open or close for its grip-friendly lid-lifter in unfavorable weather conditions. The weight limit for this roof box is 75kg.

Because of its immense size, you might be worried about access to your car’s trunk. But you don’t have to worry because it sits slightly ahead on the roof of your vehicle, so you can get the full trunk access without hitting your roof box.

Thule Force Cargo Box:

Thule Force Cargo Box

This sleek roof box is another product from Thule. Despite looking great, the performance is good also. But we kept this at number 2 because of its mounting system.

To install it on the roof of your vehicle, you need to open the mounting tools first. Then you have to set the box in the center of the roof bars. The installation process is a little trickier, and you have to work correctly. Still, the installation process only took less than 5 minutes.

The Thule Force Cargo Box is available with a pre-installed quick-grip mounting system. So the installation process for this roof box is tool-free. The lid is very durable and functional with a diamond-textured finish. Its aerodynamic shape is conducive to reducing drag and resist air.

Yakima Skybox Carbonite Cargo Box:

Yakima Skybox Carbonite

This magnificent large 21 cubic feet roof box weighs 75 lbs. It can carry only 28 kg because of its size. At the 21 cubic feet volume range, the other Thule roof boxes can carry more weight.

The Yakima Skybox can also give you access from the dual side, and it is available with a super latch, which makes the opening and closing easier. The tapered exterior of this roof box is stunning. And it can reduce drag. You can install it without any tools.

To install it, You have to follow the following steps only: 

  1. Open the lid
  2. Release the clamps
  3. Loosen the thumbwheels
  4. Position the roof box on your roof rack crossbars
  5. Slide it back so that the clamps engage the load bars
  6. Tighten the thumbwheels
  7. Then engage your lever clamps.

That’s it! After completing these steps now, your Yakima Skybox Carbonite is correctly installed on the roof of your vehicle, and it will not slide down from your roof bars. If it does slip, open the lid of your roof box and tighten the levers to secure it.

The price of this roof box is as like the Thule. Now you can ask us why you should buy the Skybox? Then the answer is – It is available with lid stiffeners, which makes it much durable than the Thule. Moreover, the installation process for this roof box is more comfortable than the Thule also.
