Designed to provide safe, compliant storage solutions during transit, overpack drums are ideal for the most demanding environments. The 180 Gallon Poly-Overpack Drum delivers reliable, regulation-compliant storage of small transformers, and its innovative Tight Grip feature makes achieving a tight seal fast and simple in time-sensitive situations. When a small, stackable salvage drum is needed to transport 5-gallon pails, bottles and cans that are at risk of leaking, consider the 20 Gallon Poly-Overpack Salvage Drum. It's UN and DOT-rated, making it perfect for use as a portable spill kit container.
