At the end of every coffee preparation comes cleaning the portafilter. One essential tool for this is the knock box, which is used to knock out the portafilter and collect the spent coffee pucks. Due to its size, it usually takes up a fair amount of space in the coffee-making area.


rb.crafts turns this into an advantage by reimagining the box with a refined wood finish that gives it a subtle yet exclusive character. You can also choose between a stainless steel or black inlay, allowing the box to blend elegantly into any setup while radiating warmth and premium quality. At the same time, the knock bar—with its thick yet soft rubber coating and solid aluminum core—effectively dampens the sound created when knocking out the portafilter.
