The Justrite Safety Drum Funnels is a large steel funnel with self-closing cover and 6" flame arrester. These funnels are specially designed for use with flammables. Wide mouth funnels are a must when transferring liquids into the relatively small 2" bung on a 30- or 55-gallon 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. The 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 (like sparks from powertools, static electricity or cigarettes) from reaching the drum's flammable contents.
