We've found some un-used (still packaged) aluminium roof bars in our garage. The roof bars fix on to your car's roof rails. These bars are suitable to use with roof box, cycle rack and ski carrier. They are lockable and come with the keys ( 2 provided).
The roof bars come with the fitting Alan key.
The length is 120cm -I've taken a photo of the car models they work with, but if you can't see it let me know.
