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.

Helpful Tips:

Sometimes when a bag becomes quite full a vacuum may form underneath making it hard to remove the bag from the tube. A solution to this is to drill a couple of holes in the base of the tube, which will prevent the vacuum. Another solution is to tie a knot in the top and lay the tube on the ground. This lets the waste settle on the side, reducing the vacuum effect, making it easier to slide out the bag.
If you're having trouble joining the Thumpa Rod and Rubber sleeve together, please do not bang them together. This friction can cause the two parts to bind together. Instead, apply a small amount of olive oil or other food-grade lubricant to the parts and join together.
