Prevent dangerous spills when transferring flammable liquids with Justrite® Drum Funnels. A must for transferring liquids into small 2" bung on a 30- or 55-gallon (1 & 20 L) drums. These funnels comply with EPA and OSHA regulations and are FM approved. Larger funnels accept a lock to prevent unauthorized access, while self-close models use a fusible link that melts at 165F (74C), closing the cover automatically.
