Frequently Asked Questions (FAQs)

1. What do you put in a rooftop box?

Bulky, lightweight things fit well in roof boxes: Things that take up a lot of space but don't weigh a ton are good items to put up top in roof boxes. So, things like tents, sleeping bags, sleeping pads, pillows, camp chairs, etc. are good options.

2. Do you need straps for a roof box?

You'll find that most roof boxes are fitted with elasticated internal straps to help you secure its contents, so make sure these are used, and you take the time to ensure that they fit snugly over the box's contents.

3. Do roof boxes damage your car?

Can roof bars damage my car? If your roof bars aren't fitted correctly, then they can indeed damage your car. For example, if screws or clips are over-tightened, then the tracks in your roof or connection points can become warped or go out of shape.
