A pair of Rak's unique telescopic aerofoil crossbars with key-locking roof mounts, for vehicles without conventional gutters. Adjustable crossbar with computer designed aerodynamics and tubulators for quiet running. The roof mount Type 3 sits on the edge of the roof and usually secures to the door frames by special straps (custom brackets for various vehicles). The rack is clamped onto the vehicle by tightening a hidden internal tension rod that retracts the aerofoil crossbar until the straps tighten and thereby hold the rack down onto the roof. Accepts the wide range of RAK accessories.
