Abstract
A closure for a pressure vessel of the type in which the pressure vessel door is preferably slidably attached to the pressure vessel by door retention assemblies. The door is constructed of a plate member to which bars are attached at opposing edges of the door. Slider portions are inset in a portion of the surface of each slider bar to enhance sliding contact with the door retention assemblies in sliding door embodiments of the invention. A plurality of reinforcing members span the plate member between slider bars and taper from a maximum elevation at or adjacent the center of the reinforcing member to a minimum elevation at the edges of the reinforcing member, where a flange sandwiches the slider bars between the plate member and the flange.
