History
The ‘Knock Box’ name is rather self-explanatory. It comes from the fact that one knocks a portafilter against it to get rid of the used coffee grounds within. In its larger form, it is essential equipment for any coffee shop. However, in smaller sizes it can also be very useful for small businesses that do not primarily serve coffee, or even for coffee enthusiasts at home.
This Rocket model is constructed from stainless steel and heavy-duty rubber. Thanks to the meticulousness and ruggedness that makes Rocket's reputation, there is no doubt that their knock box will last you many long happy years. Its narrow dimensions (10 x 10 x 15 cm) make it a practical object that doesn't take too much space on counters or in your coffee station.
