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. Combine 2, 4, 6 and 8 drum modular units to create your own customized system. Use the optional joining clips to firmly lock units together. Sumps remain separate and clips can be removed for easy repositioning.
