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 or Load Bars. 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 3CR12 stainless steel and sealed with the same durable, weather resistant powder coating as the Front Runner Roof Racks. Installation hardware and fitting instructions included.
