Knock Tube


Easily collect your used coffee grounds with the Thumpa Cafe Knock Tube. This commercial-grade tube is built to handle the daily pressures of a busy cafe, designed for unrivaled durability and stability.


The top of the knock tube features a thick rubber rob that can be removed for easy cleaning. It also is designed with side collars that protect your cafe from coffee ground splatters.

The entire top piece can be removed for emptying the tube or to hold a garbage bag in place. Adjust the height of the Thumpa Cafe Knock Tube to fit your baristas’ needs by cutting it down and reattaching the top.

The tube is made with 5mm thick durable high-density polyethylene. All of the parts can easily be replaced, which means this knock tube will essentially last forever.
