How To Mount Roof Bars

These elements can be a real cat to peel, so let’s find out together how to assemble the best and what are the main characteristics they must have.
Are you wondering what roof bars are? It is easy to say, these are structures, usually in steel or aluminium, mounted on the roof of the car to fix packages or suitcases and, with special accessories, even bikes, skis and sports equipment of various types that could hardly get into the luggage rack or cockpit. It is a comfortable solution for those who have a small car and must travel with the whole family, relegating everything needed for the trip to the roof of the car.
Before buying a roof rack, you must remember to opt for certified and approved products in order not to alter the stability of the vehicle and guarantee your safety. Each bar must respect the parameters, such as the height, for example, established by the highway code, and it is possible to find different types according to your vehicle.
When you are about to choose a couple, therefore, always keep in mind the car model on which they will be mounted. Some cars are in fact equipped with longitudinal bars, also called “rails” or handrails, on which the roof bars can be fixed transversely with the appropriate fixing kit.
If your car does not have rails, the roof bars must be anchored to the roof by means of fixing points established by the manufacturer or alternatively by fixing them with the doors open with jaws. Note that the latter solution is the most common if there are no vehicles designed to use the bars.

Original accessories whenever possible

Although the purchase of original roof bars, made by the manufacturer of the individual vehicles, involves a greater expense than compatible products, it proves to be the best choice for those who want safe bars supported by their car.

Buying a few without knowing if your vehicle can accommodate them is an unconscious expense, which potentially can lead to waste your money unnecessarily. Find out from your nearest dealer if your car can mount original roof bars that have the undoubted advantage of being certified and made to measure.

If you have decided instead to opt for a compatible product, always remember to check that among the supported car models there is yours, perhaps seeking confirmation from the manufacturer before buying the roof bars in question.

The roof bars for cars with handrails are certainly the easiest to assemble, you just need to position them on the latter, taking care to respect the minimum distance between them and start working on the internal screw that pushes the tie rod towards the low, blocking the object and fixing it safely without it being able to move thanks to the pressure exerted on the two external sides of the handrails.

Assembly with fixing points is slightly more complex. The latter must in fact be highlighted first and if you are not an expert in the sector you may have some difficulties and have to seek the help of a professional in the sector. Alternatively, there are roof bars with jaws that are simply fixed inside the passenger compartment with the doors open. Once the latter are closed, you will not have to fear any movement of the bars which will remain in position until they reach their destination.

Steel or aluminum?

The two main materials with which the best roof bars are made are decidedly different, both in terms of tactile and visual feel. The steel ones are very resistant but aesthetically they leave a little to be desired. Having a greater weight also affect negatively the fuel consumption since the car to move will have to consume much more. The aluminum ones are not only lighter, therefore impacting less on consumption, but also have a pleasant aesthetic appearance and above all, the more expensive ones, are even aerodynamic to offer less wind resistance.

How much load can i carry?

Generally, the roof bars, both in steel and in aluminum, can support about 75 kg in total. Before loading your car, therefore, remember to weigh all your bags beforehand and place them on the bars in a safe way so as not to compromise the stability of the vehicle while it is in motion. You don’t want bikes or sports gear to fall at the first corner, endangering the safety of other motorists.

The heavier suitcases should always be stored in the trunk, or in any case impeccably fixed according to the instructions in the instruction manual of the bars that we invite you to consult for more information regarding the model chosen.

Consume fuel

Those who are afraid of increasing consumption should resign themselves to the idea, unfortunately mounting the roof bars, even without loading anything, leads to an increase in consumption due to the greater air resistance. The car, in fact, loses its natural aerodynamics and, just as if you always had the windows open, you will have to consider a 10% increase in consumption.

If you have no other way to transport bikes, skis or other bulky sports equipment that can hardly be easily inserted into the car, this is a tolerable compromise, however it is strongly discouraged to leave them always mounted even when you do not need to use them. As more than a few consumers point out, these are accessories with an aesthetic appearance that is not exactly pleasant and that alter the appearance of the car even if they are extremely useful.
