Reinforced flexible hoses connect to a galvanised plenum box at the base of the transparent B&L International rig, which carries a row of white disc valves along its upper branch. A Prozon board and the orange Strefa Instalatora pylon stand behind, with the orange basket of a raised boom lift near the hall roof.
