Abstract: The present invention is directed to a truck bed liner having a front end and a rear end, the liner comprising a floor, opposed side walls having side edges joining the floor, a front wall having side edges joining the side walls and a lower edge joining the floor, and support elements associated with the side walls adapted to support a shelf member extending between the side walls within the liner above the floor. More specifically, the support elements comprise side wall portions extending within the liner between the side walls and having a horizontal upper surface adapted to support the shelf member. Preferably, retainers, which may be in the form of recesses formed in the side wall portions, are provided for retaining transverse shelf support members extending from one side wall to the other side wall.

Abstract: Improved gas liquid contact sheets and contact bodies are disclosed comprising a plurality of parallel and generally vertical corrugated contact sheets, wherein the corrugations form alternating apices in the sheets, the corrugations being disposed at an angle to the horizontal and wherein the corrugations are substantially parallel and adjacent sheets are oriented such that corrugations of one sheet cross the corrugations of an adjacent sheet at intersections of the apices, the improvement comprising positioner pads positioned in apices of the corrugations of the contact sheets, such that at least about eighty percent of the intersections of adjacent sheets contain abutting pairs of the positioner pads. In addition, contact bodies in which adjacent sheet corrugations intersect proximate the edges of the contact sheets are provided.
