After making espresso, the coffee grounds can sometimes be stuck on the inside of the portafilter. With espresso knock boxes, you can easily clear out your portafilter and use it again. Simply knock your espresso filter on the knock box to remove the used coffee grounds from the filter. Knock boxes also allow you to keep all of your used coffee in one place to be recycled or used for another purpose.
Our knock boxes are deep to hold a large amount of spent grounds, so it can be used all day without having to constantly be emptied. We offer these products with a reinforced knock bar that you can use to knock out the coffee grounds. The reinforced bar is also removable, so the contents of the box can be emptied easily. In addition, our espresso knock box is made of durable stainless steel, allowing it to withstand hard knocks.
