About the car: cars with roof bars
A roof box needs roof bars fitted on the car. Without bars it cannot be fixed, and the bars must be fitted according to the instructions of the car maker or of the bars.
Before choosing a box, check the type of fitting of your bars. Some boxes fix with a U-bolt fitting, others with a 20 mm T-bolt system, and choosing correctly avoids a wrong fitting and wasted time.
If you already have roof bars fitted, you choose the box by two things: how much volume you need and how much access you want to your luggage. The guide to roof-mounted and rear-mounted bike racks also helps you compare with other accessories you can fit on the bars.
How to choose the right box
For a 400-litre box, the guide on Carbon Look 400 explains what the box is useful for and the fitting steps. The box has 400 litres and carries 75 kg, with a U-bolt fitting on the roof bars.
For a smaller box, MatBox has 320 litres, is 128 cm long, 90 cm wide and 38 cm high, with an 80 mm U-bolt fitting and opening on one side.
Technical details and what to watch for
- Capacity is read as two numbers: the volume in litres and the maximum weight. For example, Carbon Look 400 has 400 litres and carries 75 kg.
- The weight of the box is deducted from the capacity of the bars. With bars that carry 75 kg, a 10 kg box leaves 65 kg for luggage.
- The height of the box adds to the height of the car. Measure the total height before a garage or a car park with a barrier.
- Boxes can open on one side or on both sides. Choose according to where you will need access to your luggage.
- Many boxes have a key lock, useful when you stop on the road.
- Every box comes with fitting instructions and the tools needed for fitting.
- The total load, that is luggage plus box, must stay below the lower of the limits of the box and the bars. If the bars carry less than the box, the limit of the bars is the one that counts.
