Justrite wide mouth funnels are a must when transferring liquids into the relatively small 2-inches bung on a 30- or 55 gallons drum. Justrite offers funnels with superior safety features that make them ideal for use with solvent, thinner, oil and paint wastes. Heavy 18-gauge galvanized steel with electrostatically applied epoxy powder-coat paint provides durability and chemical resistance. All funnels comply with EPA and OSHA regulations and are FM Approved. Larger funnels accept a lock to prevent unauthorized access. Funnels intended for use with flammables are fitted with a brass flame arrester that absorbs and dissipates heat, preventing any external ignition source from reaching the drum's flammable contents. FM Approved. Measures 4-1/2-inches diameter by 4-1/2-inches height.
