Comes in a set of (4) four, 1 pair of front foot rails and 1 pair of rear foot rails (left and right hand side per pair). Fits to the Land Rover All-New Discovery's existing mounting points. No drilling or modification required. Foot rails follow the contours of the vehicle's roof line providing a sturdy base to fit the Front Runner Slimline II Roof Rack. These Foot Rails contain 1 opening to access a Front Runner under rack mount table (1 smaller TBRA018 or 1 larger TBRA017). Made of steel and sealed with the same durable, weather resistant powder coating as the Front Runner Slimline II Rack. Installation hardware and fitting instructions included.
