Questions & Answers

Ask a Question
  • Does the 5 gal poly pail come with a spigot or do you have to pour out of it? Also, what is the Hazmat fee for 5, 5 gal poly pails? I work for the state of Virginia. If our agency orders a certain number of 5 gal poly pails would we get a discount per unit?

    It doesn't come with spigot.
