Key points

Before choosing a roof box, verify its compatibility with your vehicle and the maximum allowed load, as well as the opening mechanism and fixation system. Measuring the roof before purchasing also helps compare options.

Opening: Check access from both sides

When comparing roof boxes, explicitly check if each model can be opened from both sides. Volvo recommends reviewing this aspect before purchasing.

Look for the answer in the product information. If it is not clear, confirm it before deciding.

Fixation: Identify the system and quick fittings

Check what fixation system the roof box uses and if it incorporates quick-release fittings; Volvo recommends considering both data points.

Note the specification for each model. If any data is missing or unclear, confirm it before comparing them.

Compatibility and maximum load: Check the limits

Before deciding, check the compatibility of the roof box with the vehicle and what the maximum allowed load is. Do not assume these data or substitute them with information about the opening or fixation.

If the information consulted does not clarify compatibility or maximum load, resolve those doubts before choosing.

Measure the roof before buying

Autohero recommends measuring the size of the car's roof before buying a roof box. Note the measurement to consider it when consulting options.

The measurement alone does not confirm compatibility: also check that the roof box is compatible with the vehicle.

Compare the answers before deciding

Gather for each model the information about opening from both sides, fixation system, quick fittings, compatibility, and maximum allowed load. Also note the roof measurement you have taken.

If a specification is not clear, consult it before making the decision. These checks help compare options, but they do not allow assuming compatibility or calculating the maximum load.
