This pair of rails, with integrated mounting feet, is used to mount the Front Runner Slimline II Roof Rack to the Nissan Frontier 3rd Gen. Comes in a set of (2) two. Left-hand side and right-hand side. Easy installation, no drilling into the Nissan Frontier's roof required. These Foot Rails contain 1 opening to access Front Runner under rack mount tables (1 smaller TBRA018 or 1 larger TBRA017). Does not use any additional tracks or feet which gives this setup a stock look. Made of steel and sealed with the same durable, weather-resistant powder coating as Front Runner racks. Installation hardware and fitting instructions are included.
