What is the load capacity of Arcos M, L and XL?

All sizes have a maximum load capacity of 50 kg. This means you can safely carry bulky items like luggage, camping gear, and sports equipment up to that weight.

Can I open both sides of the box?

Yes. The Thule Arcos boxes feature dual-side opening, allowing easy access from either side of your vehicle.

Do Arcos boxes fit all roof bars?

Thule Arcos boxes fit most Thule and compatible roof bar systems. Always check the maximum load capacity of your bars and vehicle before installation.

How secure is the Thule Arcos box?

Each Arcos box comes with a central locking system, designed to keep your gear safe and secure while on the road. The lock secures both the lid and the box to your roof bars.

Are Arcos roof boxes weatherproof?

Yes. The Thule Arcos series are weather-resistant and durable, keeping your gear dry and protected against wind, rain, and road conditions.

Can I install the Arcos roof box myself?

Yes. All Arcos sizes install quickly using the Power-Click quick-mount system, which gives a secure attachment with audible feedback.

Is the Arcos XL significantly larger than the Large model?

Yes. The XL model offers greater volume and length, making it a better choice for longer items or larger families. It’s ideal for ski trips, holidays, and equipment transport.

What vehicles can use the Arcos boxes?

Arcos boxes are compatible with most cars, estates, SUVs and MPVs that have suitable roof bars. Always check vehicle roof load limits in your owner’s manual.

Do I need special tools to fit the Thule Arcos box?

No. The Power-Click mounting system is tool-free, so you can fit and remove the box without special equipment.

Can I leave the Thule Arcos box on all year?

It’s generally fine to leave the box on the vehicle when not in use, but we recommend removing it if it won’t be used for long periods to reduce aerodynamic drag and fuel consumption.

Is the Thule Arcos box suitable for ski equipment?

Yes. All Arcos sizes have enough volume and secure mounting, making them ideal for ski bags and sports equipment when paired with the correct carriers.
