This shell-scheme stand displays equipment for fixing duct insulation: blue and red welding units, insulation pins and perforated anchor plates on the wall, and a section of rectangular duct lined with mineral wool in the foreground. A foil-wrapped round duct carries a yellow award rosette, and framed certificates hang on the back wall.
