Attached to the rear load bar this roller makes it easy to slide longer objects onto the load carrier. The risk of damaging the car roof or the back of the person doing the loading is greatly decreased. As it is placed in the rear t-track of the Heavy-duty Crossbar it is not in the way when used together with other load accessories. The load rests on the load bar - not on the roller - for maximum safety. Available in two lengths, 65 cm and 110 cm. Aluminium profile covered with soft plastic (TPE) surface.
