The Onto is a great solution for those with small cars but lots of luggage, or anyone who wants an extra 300L of cargo space which is super easy to access.
Due to its low mounting position vs a roof box, the Onto is amazingly easy to use, and when you want to reach your hatch or boot it tilts down with a foot pedal system, allowing easy access whenever needed.
Although the box is a foldable type, it sacrifices nothing in terms of its water resistance or strength. This is done through the use of water resistant materials and sealed zippers. The rear mounting position also provides some shelter when driving in severe rain.
When not in use the box folds down into a neat and easy to handle unit, making storage and fitting so much easier. Security is handled via unique buckle locks on the storage area, and a lock on the towball attachment mechanism, ensuring that it's a tough job to access the Onto for any would-be thief.
For added safety and legal compliance on the road, the Onto also features integrated tail lights and plate holder.
Installing the box is very straightforward, it mounts directly to your vehicle's tow ball and even includes an exact sized towball in the package. Please refer to the fitting instructions for more details before ordering.
You can key alike your Thule products by purchasing lock cores separately. If you have any further questions about key matching please contact us for more information.
