Abstract: This invention relates to the art of securing cargo in the bed of a pickup truck. A slotted bar is secured to the upper inside wall in the bed of a truck where the structural flange is formed around the bed. When the rail is mounted on a vehicle it provides a plurality of tie down locations and increases the structural strength of the side walls. The tie down does not interfere with a bed cover. The tie down is fabricated from one or multiple pieces that are linkable to extend the length of the tie down and allow for configuration changes based upon the dimensions of the truck bed.
