When it comes to enhancing your vehicle's storage capacity, a car roof box is an excellent solution. As a leading car roof box supplier, we understand that choosing the right mounting system is crucial for a safe, secure, and hassle - free experience. In this blog, we'll explore different mounting systems for car roof boxes and help you determine which one is the best for your needs.
1. Saddle - Type Mounting System
The saddle - type mounting system is one of the most common and traditional methods for attaching a roof box to your vehicle. This system typically consists of two large, U - shaped brackets that straddle the roof rails of your car.
One of the main advantages of the saddle - type mounting system is its stability. The large contact area between the brackets and the roof rails distributes the weight of the roof box evenly, reducing the risk of the box shifting during transit. This makes it a great choice for long - distance travel and high - speed driving.
Another benefit is its ease of installation. Most saddle - type mounting systems can be installed without the need for any special tools. You simply place the brackets over the roof rails, tighten the bolts or clamps, and you're good to go. This user - friendly design is ideal for those who are not particularly handy or who want to quickly install and remove the roof box as needed.
However, there are also some drawbacks to the saddle - type mounting system. One of the main issues is its compatibility. Not all vehicles have roof rails, and even if they do, the shape and size of the rails can vary widely. This means that you may need to purchase additional adapters or choose a different mounting system altogether if your vehicle's roof rails are not compatible.
Additionally, the saddle - type mounting system can be relatively bulky. The large brackets can add some extra height and width to your vehicle, which may affect its aerodynamics and fuel efficiency. It can also make it more difficult to park in low - clearance areas.
2. Clamp - On Mounting System
The clamp - on mounting system is another popular option for attaching a roof box to your vehicle. This system uses a series of clamps to secure the roof box directly to the vehicle's roof or to the crossbars.
One of the key advantages of the clamp - on mounting system is its versatility. It can be used on vehicles with or without roof rails, as long as there are suitable crossbars or a flat roof surface. This makes it a great choice for a wide range of vehicles, including sedans, SUVs, and minivans.
Another benefit is its compact design. Unlike the saddle - type mounting system, the clamp - on system does not add as much bulk to your vehicle. This can help to improve its aerodynamics and reduce fuel consumption. It also makes it easier to park in tight spaces.
However, the clamp - on mounting system also has some limitations. One of the main concerns is its strength. Since the clamps rely on friction to hold the roof box in place, there is a risk of the box shifting or coming loose if the clamps are not tightened properly. This can be especially dangerous at high speeds or during sudden maneuvers.
Installation can also be a bit more challenging compared to the saddle - type system. You need to ensure that the clamps are positioned correctly and tightened to the appropriate torque to prevent any movement. This may require some trial and error, especially if you are not familiar with the installation process.
3. Track - Mounting System
The track - mounting system is a more advanced and specialized option for attaching a roof box to your vehicle. This system uses a set of tracks that are installed on the vehicle's roof, and the roof box is then attached to the tracks using a sliding mechanism.
One of the main advantages of the track - mounting system is its adjustability. You can easily move the roof box along the tracks to change its position, which can be useful for balancing the weight of the load or for accessing different parts of the vehicle. This flexibility is particularly beneficial for those who carry a variety of items in their roof box.


Another benefit is its security. The track - mounting system provides a very secure connection between the roof box and the vehicle. The sliding mechanism is designed to lock the roof box in place, preventing it from moving or coming loose during transit. This makes it a great choice for valuable or fragile items.
However, the track - mounting system also has some drawbacks. One of the main issues is its cost. The tracks and the sliding mechanism are more complex and expensive to manufacture than other mounting systems, which means that the overall cost of the roof box with a track - mounting system is usually higher.
Installation can also be more complicated. You need to drill holes in the vehicle's roof to install the tracks, which may void the vehicle's warranty if not done correctly. This requires some technical expertise and may not be suitable for DIY installation.
4. Adhesive - Mounting System
The adhesive - mounting system is a relatively new and innovative option for attaching a roof box to your vehicle. This system uses a strong adhesive to bond the roof box directly to the vehicle's roof.
One of the main advantages of the adhesive - mounting system is its simplicity. There are no brackets, clamps, or tracks to install, which means that the installation process is quick and easy. You simply clean the roof surface, apply the adhesive, and attach the roof box. This is a great option for those who want a hassle - free installation.
Another benefit is its low - profile design. Since there are no bulky mounting hardware, the adhesive - mounting system does not add much height or width to your vehicle. This can help to improve its aerodynamics and reduce wind noise.
However, the adhesive - mounting system also has some limitations. One of the main concerns is its durability. The adhesive may not hold up well over time, especially in extreme weather conditions or if the vehicle is exposed to a lot of vibrations. This can lead to the roof box coming loose or detaching from the vehicle.
Removing the roof box can also be a challenge. Once the adhesive has been applied, it can be difficult to remove the box without damaging the vehicle's roof or the box itself.
Which Mounting System is the Best?
The answer to this question depends on several factors, including your vehicle type, your usage requirements, and your budget.
If you have a vehicle with roof rails and you need a stable and easy - to - install mounting system, the saddle - type mounting system may be the best choice for you. It provides excellent stability and is relatively inexpensive.
If you have a vehicle without roof rails or if you need a more versatile and compact mounting system, the clamp - on mounting system is a great option. It can be used on a wide range of vehicles and does not add much bulk.
If you need a highly adjustable and secure mounting system, especially for carrying valuable or fragile items, the track - mounting system may be worth the extra cost. It provides excellent adjustability and security, but it is more expensive and difficult to install.
If you want a simple and low - profile mounting system, the adhesive - mounting system may be suitable. However, you need to be aware of its limitations in terms of durability and removal.
