Galvanized frame with 4" twin rubber blades which removes large amounts of liquid while the built-in splash guard prevents liquid from spilling over the frame. The 30" has a reinforced handle socket fixed to its frame for added strength with 6 reliable spot welds. Available with black rubber, white rubber or red neoprene rubber. Black rubber is a good general purpose material for cleaning areas where oil and heat resistance is not required. White rubber is weather and heat resistant and is therefore excellent to prevent the spread of bacteria. Our red neoprene rubber is resistant to heat, chemicals and oils.
