The Tubbi knockbox is the perfect accessory for home baristas! Its extremely tough and resists well to knocks thanks to the food safe rubber bar reinforced with stainless steel. The rubber bar is designed to absorb the energy from the portafilter to minimize the noise. A non-slip rubber pad on the bottom prevents it moving about the place and also helps to reduce the noise.
The knockbox may be small but it can comfortably hold 15 double pucks of coffee before it needs emptying. To empty just lift the rubber bar out and discard the coffee as you wish. You can just give it a rinse in mild detergent, but the plastic tub is dishwasher safe, if you prefer.
