Made of plastic, they are used with antistatic cloths to dust floors. They are available in two sizes - 40 and 60 cm. The lamellar tool is used only with soaked cloths for floor dusting, pulling it in only one direction thanks to the particular inclination of the rubber lamellas, which adhere perfectly to the surface. This tool, being sterilizable up to 120°C is recommended in hospitals. The articulated joint is in plastic. The universal ring allows the use of any handle with a diameter ranging from 18 to 23 mm.; the articulated joint makes this tool easier to use in hampered places.
