A reversible mounting rail, for attachment to pickup truck cargo bed structures, which comprises:

• an elongated member with an elongated length having a generally L-shaped cross section comprised of two legs, one being a first leg and the other being a second leg, said two legs being 90 degrees opposed, each of said two legs having an inside wall and an outside wall, said two legs each having predetermined widths wherein said first leg is wider than said second leg and wherein said inside wall of said second leg has a predetermined width adapted to fit atop a first width cargo bed wall and said inside wall of said first leg has a predetermined width adapted to fit atop a second width cargo bed wall, wherein said second width cargo bed wall is wider than said first width cargo bed wall;
• at least one elongated holding slot running along the outside wall of the first leg and at least one elongated holding slot running along the outside wall of the second leg;
• first penetration location means located on the outside wall of said first leg for locating areas where said elongated member may be penetrated with a plurality of attachment devices for attaching said rail to a structure, said first penetration location means being a groove running along at least a portion of said elongated length of said elongated member;
• and,
• second penetration location means located on the outside wall of said second leg for locating areas where said elongated member may be penetrated with a plurality of attachment devices for attaching said rail to a structure, said second penetration location means being a groove running along at least a portion of said elongated length of said elongated member;
• thereby creating attaching capability for said rail by attachment through said first leg or said second leg or both and thereby creating a rail which may be mounted on a structure with either said first leg or said second leg in the horizontal position.
