Roof Rails
Roof rails are bars along the roof used to mount crossbars for roof boxes and carriers.
What is Roof Rails?
Raised rails have a gap under them; flush rails are integrated into the roof. Crossbars must be compatible with the rail type. The roof has a maximum load given by the manufacturer. The maximum roof load includes the weight of the crossbars and the box itself. Load figures are usually in the owner's manual, and dynamic load limits may differ from static limits for rooftop tents. Heavy roof loads raise the centre of gravity, so drive more carefully in corners and side winds.
How it works
Crossbars clamp onto the rails and carry the load.
Why it matters for your car
Exceeding the roof load can damage the roof and affect handling. Roof loads increase fuel consumption.
