What Is A Roof Box?

Types Of Roof Boxes

Most of the time, you will find two types of roof boxes in the market: hard-shell and soft-shell. As the name suggests, a hard-shell roof box is made of tough and rigid material, whereas a soft-shell roof box is made of a softer and more flexible fabric.

Hard-shell roof boxes are generally more expensive than soft-shell roof boxes. However, they offer better protection for your belongings as they are more durable and weather-resistant.

On the other hand, soft-shell roof boxes are more affordable and easier to store as they can be folded.

Size Of Roof Box

The size of the roof box will be dictated by how much extra space you need in your car. If you’re only looking to carry a few extra suitcases, then a small or medium-sized box should suffice. However, if you need to transport larger items such as bikes or kayaks, then you’ll need a larger roof box.

When you’re trying to find the right size roof box for your car, always remember to check the width as well as the length. The width is especially important because it needs to fit between the rails on your car’s roof.

Once you’ve found the right size roof box, it’s time to start attaching it to your car. Most roof boxes will come with their own set of instructions, so make sure to follow those.

Things To Consider

There are a few things to keep in mind when deciding on the size of your roof box.

  • Firstly, you’ll need to ensure that the box you choose is compatible with your car’s roof rack.

Weight Limit Of Your Car

Checks the weight limit of your car. Most cars have a weight limit for the roof, and you don’t want to exceed that.
