The width of this roof box is three feet. It comes with a dual-sided opening that makes it easier to get access to this box. And it happens because of the double-wishbone hinges on both sides of the roof box.

A ski box generally takes several hours to get installed on the roof of your car. But with the modern rooftop cargo boxes, it only takes a few minutes to install them.

With the tool-free quick install mount of the Yakima Skybox 18, the installation process has become easier. What you have to do to install this roof box is:

  1. Carefully place your Skybox 18 on your roof rack. It will be better if you have another pair of hands to help you.
  2. Adjust the mounting hardware on the box so that the spacing fits your roof rack

Moreover, the Onyx version of the Yakima Skybox 18 comes with a UV and scuff-resistant finish. Because of this UV protection, this box’s shiny black exterior won’t get damaged by UV rays.

Social Responsibility

Yakima is producing a petroleum-based product, but they are also thinking about their carbon offset and recycling efforts. Moreover, they make their roof cargo boxes from recycled ABS plastic that is recycled up to 80%. They use ABS instead of fiberglass because ABS is lighter and cheaper than fiberglass. ABS is very strong, though.

The weight of a roof box is a very important point to consider. Because, with a lighter roof box, you will be able to carry more stuff without getting your roof box overweighted.


With this box’s locking system, there is no chance of forgetting your key inside the box. After closing the box, you have to engage all three latches so that the handle can flip to the closed position. After these, you will be able to remove the key.
