Abstract: A liner in formed sheet construction which overlies a truck bed. The liner includes side walls with upper channel portions which fit restrictively between the truck bed side wall and a downturned flange of the bed rail. No exterior fasteners are necessary to secure the liner to the truck bed.

Abstract: A truck bed liner securement fixture is provided. The fixture includes a lock member having a bevelled lower part which contacts a downturned inner portion of the truck bed side wall to secure the liner to the bed. An actuator pin allows the lock member to be rotated into a locked position after installation.

Abstract: A tool box which is positioned in and supported by the bed of a pick-up truck. The tool box has a pivoting lid to allow access to the tools and a side located drip rail channel part to prevent entry of moisture into the tool box interior.

Abstract: A combination of a truck bed having side walls with an upper edge and a flange on the inner side extending downwardly from the upper edge, a liner for the bed having side walls positioned along the inner side of the flanges on the bed side wall, and a plurality of fixtures slidably securing the liner side walls to the respective flanges. The fixtures include a bracket seated on the inner side of the respective flange and on the outer surface of the liner side wall and screws, preferably of the self-tapping type, extending through the adjacent liner side wall into the bracket to hold the respective side wall against the flange in slidable relationship.

Abstract: A device for use in securing a liner in the bed of a truck having side walls with an inwardly extending upper flange and a lip extending downwardly therefrom. The device has a back portion with a clamp disposed near the upper edge thereof for engaging and gripping the lip, and a base portion extending outwardly from the back portion for engaging the truck wall and stabilizing the device. A screw is inserted through the liner and into the back portion of the device, thereby holding the liner in place while allowing relative expansion and/or contraction between the liner and the bed from temperature changes without causing distortion of or damage to the liner.

Abstract: A fixture for securing a liner in a pickup truck bed, having a body with a horizontal groove on the external side for slipping over a protrusion on the inside of the truck bed wall, and an upper inner corner for seating against a downwardly extending lip on the inwardly extending flange at the upper edge of the pickup truck side wall, whereby the fixture is held between said protrusion and lip. The fixture has an inwardly facing wall for engaging the side wall of the liner and for receiving a screw or the like extending through the liner side wall into the body of the fixture, thereby securing the liner in the truck bed without preventing expansion and contraction of the side walls in a horizontal direction.
