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. These Foot Rails contain 1 opening to access a Front Runner under rack mount table (1 smaller TBRA018 or 1 larger TBRA017). Drilling is required for fitment on some models.
