The sturdy single wall construction and flat tops and bottoms for uniform stacking make the All-Fi® transport style fiber drum an excellent choice for shipping. The telescoping design on the all fiber cover allows the lid to freely slide over the fiber drum with no struggle. The square shape of some of these drums provides optimum space utilization during storage, transit and handling, and disposal is easy as they all incinerate completely. Not all of the below fiber drums are UN rated, so you will want to check their order page to be sure. If you have more questions, email us.
