Stainless steel knock box with tamp station, a dump bin that doubles as a portafilter rest while tamping.
Breville BEA501BSS Knock Box 10 Espresso Accessory, Brushed Stainless Steel
Breville BEA501BSS Knock Box 10 in plastic and brushed stainless steel. It holds up to 10 espresso pucks, has a removable knock bar and is compact enough to store on the drip tray. Costs more than plain plastic bins.
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.
