Universal Aluminum Roof Bars 137 cm with Lock

137 cm universal roof bars: the foundation for all roof loads, secured

Before the roof box, before the cargo basket, before the bike rack, there are the crossbars. This pair of 137 cm universal roof bars provides the foundation to which everything else is attached. Made from profiled aluminum with a polished finish, they give your vehicle the look of a car ready to go—and above all, add 90 kg of roof load capacity where there was previously only bare roof.

The polished aluminum of these roof bars and their locking system

Aluminum has a decisive advantage over steel for this use: it provides rigidity without the weight. Each pair weighs just 3.7 kg, which saves roof load capacity and makes installation easy for one person. The polished profile does not rust at the first sign of rain and withstands freeze-thaw cycles: these aluminum roof bars are made to stay outdoors all year round if you wish.

The feature that makes a difference in everyday use is the integrated lock. It secures the mounting to the roof: no one will remove your bars in a parking lot, and the equipment you strap to them remains attached to the vehicle. A rare feature on cheap universal roof bars, yet a decisive one whenever you leave the car equipped in the city.

• 90 kg load capacity—enough to accommodate a loaded roof box, a cargo basket, or two bikes.
• 137 cm aluminum roof bars—a generous length that covers the width of SUVs and station wagons alike.
• Locking lock included—the bars stay on the car, even when parked for several days.
• Only 3.7 kg per pair—easy for one person to install and remove.
• Corrosion protection—the polished finish resists water and salt spray.
• Universal load-carrying base—soft roof boxes, cargo baskets, and bike racks can be strapped to it.

Mounting these bars on a bare roof: what to check first

These crossbars are designed for bare roofs, meaning vehicles without longitudinal rails and without visible mounting points. The feet rest on the door frames, then lock with the key. Two measurements to take before ordering: the width of your vehicle, which must be less than 190 cm, and the type of roof you have. If your car already has rails, you will need a model with rail feet rather than this version. Finally, installing universal roof bars requires respecting the recommended spacing between the two crossbars and checking the tightness after the first few kilometers.

What load can really be placed on roof bars?

The correct answer is always the lower of the two values: the capacity of the bars, 90 kg in this case, and the maximum roof load authorized by your vehicle manufacturer, often between 50 and 100 kg depending on the model. The latter is the deciding factor. Also keep in mind that the weight of the bars and the roof box is deducted from the payload. While driving, distribute the load toward the center rather than the ends and reduce your speed: this helps preserve both handling and the equipment.

Roof loads, a category we know well

Bars, racks, baskets, roof boxes: at Becquet Voiture, we closely monitor this family of products because it does not forgive poor choices. A poorly designed crossbar whistles, vibrates, and wears out the roof. We selected this model for its stiffness-to-weight ratio and for its lock, which is absent from most entry-level kits. Unsure about your roof type? Send us a photo of the roof, and we will tell you if this set of roof crossbars is suitable.
