- Vehicle fit: The box is described for use on a car, SUV or van. Confirm that your roof setup suits a roof box of this type.
- Access: Dual-side opening matters if you want to load from either side of the vehicle.

Using It in Practice
A roof box like this is most useful when you want to keep larger travel items separate from the cabin. Before setting off, pack the heavier items low and make sure the lid closes properly after loading. The dual-side opening is most helpful when you are loading in a tight parking space or need access from one side only.
Before You Decide
Confirm the 400L capacity, gloss black finish and dual-side opening are the version you want. Check that your vehicle roof setup can take a roof box of this type, and make sure the locking arrangement suits your travel plans.
