What is Roof Box (Roof Top Carrier)?

It is popular for holidays and ski trips. It increases air resistance, which raises fuel or energy consumption. The car's maximum roof load applies to the box, the bars and the contents together. Load heavy items in the car and light, bulky items in the box. Close and lock the lid before driving.

How it works

Clamps attach the box to cross bars fitted on the roof rails or roof fixing points.

Why it matters for your car

Check the roof load limit in the handbook and the speed recommendation of the box maker. Remember the extra height before entering garages and car parks.
