Roof box 300 litres

The maximum speed with a roof box depends on several factors, including manufacturer recommendations, traffic regulations, and driving safety. Here are some key considerations:

Manufacturer Specification

Manufacturers typically
specify a 130 km/h speed limit
for roof boxes to maintain vehicle stability and aerodynamic efficiency, as excessive speeds may compromise safety.

2. Legal Regulations

No explicit legal speed restriction exists
for roof box usage. However,
compliance with general traffic regulations
is required, particularly in terms of vehicle stability and driver control.

3. Safety Guidelines

✔
Adjust driving behavior
– Increased wind susceptibility can make the vehicle less stable.

✔
Perform routine inspections
– Verify the roof box mounting system before every trip to ensure secure attachment.

✔
Watch the weight
– Make sure you don’t exceed your car’s roof load limit or the box’s maximum capacity.

Place heavy items as centrally as possible in your roof box to evenly distribute the weight across the load carrier and vehicle. All luggage must be secured to prevent shifting. The load should not obstruct the closing of the roof box, as this may cause malfunctions in the locking system.
Make sure to adhere to the maximum roof load specified by the manufacturer. The permissible total weight of your vehicle must not be exceeded.

You’ll need to adjust your driving style due to changes in weight and height. Crosswind sensitivity increases, and the center of gravity shifts, affecting how your vehicle handles in turns and braking. Your car’s height can increase by up to 60 cm, so be cautious when entering parking garages and driving under low bridges.

For vehicles with a combustion engine, driving at 130 km/h doesn’t lead to a noticeable increase in fuel consumption—it’s about the same as the extra fuel used by a constantly running air conditioner.

For electric cars, the extra energy consumption can be significantly higher, depending on the model. On longer trips, expect to make one or two additional charging stops. If your car has a tow bar, you might want to rent a
rear cargo box
instead, as it has little effect on fuel or energy consumption.

The type of roof rack mounting varies depending on the vehicle type. Here are the common options:

•
Standard Roof:
For vehicles with a conventional roof, the rack is clamped between the door and the roof.

Standard Roof

Raised Rail:
For vehicles with an open roof railing that can be easily gripped by hand.

Raised Rail

•
Flush Rail:
A rail mounted flush on the vehicle roof, for which a custom mounting kit is required.

•
Fixed Mounting Points
: Typically, threaded inserts are installed in the roof, into which the rack is bolted using a vehicle-specific mounting kit.

•
T-Profile:
Here as well, a vehicle-specific mounting kit is used, which is anchored in the slot

he maximum load capacity of your roof box depends on several factors: the permitted roof load of your vehicle, the carrying capacity of the roof rack, and the weight limit of the roof box itself

A good comparison is air travel: Passengers are often allowed to take suitcases weighing
20 kg
each. Depending on the model, our roof boxes can hold
50–75 kg
– roughly the equivalent of
2 to 3 large travel suitcases
.

Important
: The permitted roof load of your vehicle (including the roof rack and roof box) must not be exceeded. Check your vehicle manual for the specifications. Additionally, heavy items should be placed as centrally as possible in the roof box and secured to prevent shifting.

Answer:
If your roof box does not close properly, there can be several reasons. Here are the most common issues and possible solutions:

1. The roof box is overloaded
Problem: The roof box is too full, and the lid cannot close properly.
Solution: The lid must close without pressure. Repack the box, distribute the luggage more evenly, and remove any bulky items if necessary.

2. The locking mechanism is blocked by foreign objects
Problem: Dirt, small objects or parts of your luggage are blocking the locking mechanism.
Solution: Check the lock and the rails for any foreign objects and remove them so the roof box can close properly again.

If a key breaks off, the next steps depend on whether this happens before your trip or while you are already on holiday.

1. Key broken before departure

If you have not started your trip yet, we will try to replace the roof box, depending on availability.

2. Key broken during your trip

If the key breaks while you are already on holiday, there are several possible solutions:

• Have a replacement key made by a local locksmith.

• If possible, try opening or closing the roof box from the other side.

• If this does not work, please contact us so we can help you find a solution.

3. Repair after return

Once the roof box is returned, we will inspect it and try to remove the broken key from the lock and install a new lock cylinder.

• Cost for a new lock cylinder: €30

In many cases, however, this is not enough. Then the entire locking strip has to be replaced. This means the old strip must be drilled out, replaced and riveted back in place.

• Cost for replacing the locking strip: €80

Answer:
For vehicles with combustion engines, fuel consumption at a typical motorway speed of 130 km/h usually does not increase significantly. The additional consumption is roughly comparable to driving with the air conditioning on continuously.

For electric vehicles, the additional energy consumption can be significantly higher depending on the model. For longer journeys, you should therefore plan for about one or two extra charging stops.

If your vehicle has a tow bar, renting a rear cargo box may also be a good alternative. A rear box usually does not have a significant impact on energy or fuel consumption.

In most cases, the whistling sound comes from the roof rack. Please make sure that the rack is properly mounted and that all openings and holes on the box are sealed.
