A method and apparatus particularly suited to the manufacture and assembly of cage-like, substantially cylindrical structures made of long, slender tubular components which, by themselves, are not self-supporting, employs an exo-skeleton structure to assemble cage-like, tubular structures in pie-shaped, longitudinal segments while in a horizontal or vertical position utilizing longitudinal or circumferential attachments. The apparatus comprises at least two segments which permit construction of subassemblies of the cage-like, tubular structure and their transportation, if necessary, to a remote site where they may be finally assembled.

An access door for a boiler or furnace has a water-cooled jacket mounted on a door panel frame for use in high temperature regions of furnaces and boilers. The door is large enough to permit a stretcher to pass through unobstructed. The water-cooled jacket has a series of baffles which direct water in a serpentine path through the jacket. Plant water, as opposed to boiler quality water, may be used to cool the door. A viewing port may be provided in the door as well.
