Frequently asked questions
- Will a roof box fit any car?
- Most boxes mount to roof bars, so you first need compatible bars and a roof rated for the load. Always check your vehicle's maximum roof weight before fitting.
- How much does a roof box affect fuel economy?
- Any roof load increases drag and uses more fuel, especially at motorway speeds. A streamlined box has less impact than a roof bag or open rack.
- Can I leave a roof box on all year?
- It is best removed when not in use to cut drag, noise and wear. If left on, check the mountings periodically and remove it before using an automatic car wash.
