Roof bars are not included, so check your existing roof bars, vehicle handbook and spacing before installation.At 100cm long and 8.9kg, this car storage box gives you a useful balance of added storage and manageable size. It is a strong option when you want extra capacity but do not need the larger footprint of our 320L car roof box.Lockable storage for peace of mindTravel days usually mean stopping for fuel, food, coffee or a quick break. The built-in central locking system helps keep the lid secured, with keys included so you can lock your belongings before setting off again.The roof box opens from one side for straightforward access at rest stops, while the aluminium lock and polypropylene hinges keep the mechanism practical and simple. Anti-skid support helps keep stored items steadier while you drive, reducing unnecessary movement inside the box.Shaped for smoother journeysA roof box should add storage without making the journey feel harder. The aerodynamic design is shaped to reduce wind resistance and excess noise, helping the box travel more smoothly once fitted correctly to suitable roof bars.That makes it useful for motorway drives, holiday routes and longer family journeys where comfort matters as much as packing space. Pair it with other road-trip essentials, such as a 24L electric cool box, to keep the car organised from driveway to destination.The Vonhaus PromiseTrusted by thousands of customers, with more than 20,000 reviews on Trustpilot.
