Low-Profile EcoPolyBlend™ Accumulation Centers only measure 5-1/2” (140-mm) high for easy handling of drums. Made of recycled polyethylene, these accumulation centers are nearly impervious to chemicals, including acids and corrosives. Seamless construction eliminates leaks, making these ideal for drum filling and dispensing operations. Self-locating grates won’t ride-up, and are removable for easy cleaning.
