Abstract: A double opening lid for use in a truck storage box. A first lid opens along a longitudinal dimension of a truck storage box to give full access to the entire interior of the truck storage box. Additionally, two side lids mount along a line perpendicular to the longitudinal dimension of the truck storage box lid open upwardly and inwardly for easy access from the side of the truck in which the truck storage box is mounted. The two side lids will ordinarily be mounted somewhat above the plane of the first lid to provide for run off of rain or other materials. Ordinarily, a frame is employed to provide better rigidity and durability for the lid. Thus, the double opening lid opens longitudinally to give access to the entire truck storage box, and conveniently opens from either side to give easy access from the side of the truck on which the truck storage box equipped with this double opening lid is mounted.
