All OverPacks are DOT-approved and X-rated for use as salvage drums. They help companies conform to federal regulations when shipping damaged or leaking containers of hazardous materials or absorbents contaminated with hazardous substances. OverPacks are sturdy and chemical resistant for years of use. Integrated forklift ledges and handles (on containers with wheels) make them easy to lift, move or carry. Avoid the extra expense of a dolly when you buy a wheeled OverPack, which provides you with great versatility in a single integrated product.
