Best Knock Boxes
As an Amazon Associate I earn from qualifying purchases.
A knock box is the unglamorous hero of a tidy espresso bar. Instead of banging spent pucks into the trash and making a mess, you knock them into a padded bar and empty grounds in one go. It keeps your counter clean and your workflow fast. At home, look for a rubber-cushioned knock bar that protects your portafilter, a non-slip base, and a size that suits your counter space. Removable inserts make cleanup easy. The knock boxes below cover compact countertop models through larger, heavier options for high-volume home use.
