This Thumpa is an 860mm tall knockout tube which was designed with durability in mind. Commercial coffee waste bins need to withstand being hit, bashed, and dropped without coming apart. The Thumpa is virtually indestructible and perfect for the demanding needs of a busy coffee shop. Using high density, shock-resistant polyethylene (HDPE), the Thumpa can really take a beating! The flared collar retains excess splatters. The slotted bar inserts and removes easily for cleaning, replacement, and maintenance. The top is also easily removed for easy emptying or for use in conjunction with a waste bag. The hole in the top allows you to clip a cloth to your thumpa for improved workflow and cleanliness.
