Comes in a set with 2 left-hand side and 2 right hand side rails. Fits to the Mercedes-Benz V-Class's existing mounting points. No drilling or modification required. Foot rails follow the contours of the vehicle's roofline providing a sturdy base to fit the Front Runner Racks. These Foot Rails contain 2 openings to access a Front Runner under rack mount table (1 smaller prep table and 1 larger camp size table). Made of high strength steel and sealed with the same durable, weather resistant powder coating as the Front Runner Roof Racks. Installation hardware and fitting instructions included. Note: Not suitable for vehicles that are fitted with a glass roof/Sunroof.
