【Extended Roof Box】Carry plenty on top of your car! With 496L of storage, there's plenty of room for fishing rods and skis

When it's time to enjoy outdoor activities with the family, the problem of carrying a lot of luggage becomes a concern. When outdoor gear is added to the usual luggage, the car interior becomes cramped. In such cases, a large-capacity roof box provides a neat and spacious solution.

A large-capacity roof box that can carry up to 10 snowboards

This summer, I'm in the mood to enjoy outdoor activities like surfing, stand-up paddleboarding, and fishing with my family. During my research, I was struck by the new release "Granfore Max Large" from the system carrier brand Terzo. It’s a large-capacity roof box that balances high functionality and aerodynamics.

The large loading capacity of the very popular "Granforma series" is an impressive 496L. It can carry up to 10 snowboards and as many as 12 sets of skis. Quite reassuring! With this, you can transport all sorts of outdoor gear, from surfboards and fishing rods to coolers and tents.

Easy operation for flexible adjustment

The standard loading capacity is 416L. With simple operation, if you increase the height by 4cm, the loading capacity rises by a whopping 80L.

The height and capacity can be adjusted as needed, making it possible to have "a compact amount on the way there and pack it full on the way back." You can relax even if your luggage increases due to souvenirs or shopping while out. Also, if you put in fishing rods or coolers, the outdoor smells won't fill the car on the way back. This way, you can avoid smells sticking to the interior or seats.

Comfortable drive with a nose-down design

The cover opens from both sides and is easy to install with a small smart clamp. The small fasteners don't interfere when loading luggage, which is surprisingly helpful.

The design features a streamlined nose-down shape. It allows airflow without significantly increasing air resistance. Even with the roof box attached, you can drive comfortably as usual and enjoy a pleasant ride.
