Wide-mouth funnels fits 2" bung on a 30- or 55-gallon drum. Heavy, 18-gauge galvanized steel with electrostatically applied epoxy powder coat paint provides durability and chemical resistance. 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 power tools, static electricity or cigarettes) from reaching the drums flammable contents. Larger funnels accept a lock to prevent unauthorized access. Self-close models have a fusible link that melts at 165¿F. The cover then automatically shuts in case of a fire to extinguish the flames. All funnels comply with EPA and OSHA regulations and are FM approved. Ships Direct F.O.B. Mfg.
