Double knock box drawer

What is a knock box drawer

The knock box drawer, also known as a knockbox, is used to catch used coffee grounds after knocking out the portafilter or filter. It slides into the work counter or coffee machine base and allows quick and clean removal of coffee residue without unnecessary cleaning around the machine.

How to spot wear

Over time, the drawer can become deformed, jam when sliding out, or the locking or handle mechanism may become damaged. Corroded or scratched surfaces can be less hygienic and make it harder to keep the work area clean. A loose or poorly sealing part also increases the risk of grounds spilling out.

When it's time for a replacement

A functional drawer ensures smooth coffee preparation and keeps the work area clean and safe. A damaged part slows down operation and can cause a mess in the surrounding area, which is especially inconvenient in businesses with a high volume of coffee preparation.

How to choose the right part

When choosing a replacement, pay attention to the dimensions and mounting method, which must match your specific machine or base. Always check the exact compatibility in the product table.
