Abstract: A cargo securing system includes a forward cab protector rack and a rear tailgate rack interconnected by side beams. The forward rack includes upper and lower corner supports each having sections with an extension member telescopically secured within and pinned to one another whereby the rack extends above the truck cab. The upper front section can be removed and stored in a horizontal position. The rear rack includes corner supports each having upper and lower sections movable relative to one another to provide a rack at a height equal to the height of the sides of the truck bed or a rack extending above the truck bed sides, respectively. Cross beams extend laterally between the upright corner supports and side rails extend between the front and rear corner supports at adjusted elevations. The cross beams, side rails and extended upright supports may be stored by pinned connections with the supports for the rack secured to the sides of the truck bed.
