Closer view of the Rygel counter and a wall-mounted galvanised duct section with a round transition fitting, next to the slogan "Producent kanałów wentylacyjnych". Large photo panels on stand E3.11b show insulated rectangular ducts and duct openings in buildings. A small duct sample rests on a wooden pallet on the counter.
