For decades, Eagle's growing selection of plastic barrel drums has met the need for safe storage and transport of solid materials. This 20-gallon yellow nestable lab pack barrel drum can be stacked to minimize storage space requirements. The tapered bottom allows suction-free separation. Ideal for secure storage, handling, and transportation of hazardous materials, spill containment, cleanup of hazardous materials, original shipping container, bio waste disposal, and incineration. For a secure closure, metal bolt ring closures require a torque wrench to tighten or untighten, providing a more secure closure. A torque wrench is recommended to ensure proper closure and UN Rating requirements.
