A knockbox is also called a “bash bin” or “coffee column”. It is used to discard spent espresso grounds (puck). This is a knock box made of stainless steel and has a sturdy bar known as the bash bar. Portafilters are tapped against the bar to release the puck.
Cafes keep these coffee knock boxes usually near the grinder over the counter or fit inside it
