Comes in a set of (2) two, the left-hand side and right-hand side. Fits both the Chevrolet Colorado Crew Cab and GMC Canyon. The foot rails follow the contours of the vehicle's roofline, providing a sturdy base to fit the Front Runner 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 high strength steel and sealed with the same durable, weather resistant powder coating as the Front Runner Roof Rack. Installation hardware and fitting instructions included.
