The Rattleware Stainless Steel Knock Box is a compact, square-format espresso tool designed for home baristas and café workstations where counter space is limited. Built from stainless steel with a hammer-finish coating and fitted with an integrated splash guard and rubber gasket, it handles used puck disposal cleanly and quietly. Measuring 6" x 5.5" x 4", it fits neatly beside an espresso machine without crowding the workflow.
The integrated splash guard catches errant grounds and water that fly off a spent puck during the knock, keeping the surrounding counter dry. For anyone who has wiped down a backsplash after every shot, that containment makes a real difference across a busy morning session. The rubber gasket seals the base of the bar, dampening the sharp crack of the portafilter strike into a duller thud, noticeable in shared spaces or early-morning home kitchens where noise matters.
The stainless steel body resists corrosion from the wet, acidic grounds that accumulate in a knock box over the course of a day. The hammer-finish coating adds a layer of surface resilience that helps the exterior hold up against the minor scuffs and impacts that come with regular counter use, while giving the box a professional appearance that holds up alongside commercial equipment.
At 6" x 5.5" x 4", the Rattleware Knock Box occupies a small footprint that fits on a home espresso bar or a cramped café counter without requiring a dedicated shelf or drawer. The square profile makes it easy to tuck into a corner or position flush against a machine.

The Rattleware Knock Box suits home baristas and small café workstations where counter space is at a premium. The compact 6" x 5.5" footprint, splash guard, and noise-dampening gasket make it a practical daily-use tool for anyone pulling multiple shots and wanting a clean, contained disposal method.
This knock box is not designed for high-volume commercial environments where a larger-capacity or wall-mounted knock drawer would be more practical. It does not include a removable inner liner or drainage port, so it requires manual emptying and rinsing.
The Rattleware Stainless Steel Knock Box ships as a complete unit with the knock bar, splash guard, and rubber gasket included. No additional components are required to begin use.
The rubber gasket on the Rattleware Knock Box cushions the portafilter strike against the bar, reducing the sharp crack to a softer thud. The difference is noticeable in quiet home kitchens, though some impact sound is inherent to any knock box design.
The Rattleware Knock Box does not have a removable inner liner. Cleaning involves emptying the grounds, rinsing the stainless steel interior, and wiping down the splash guard. The compact size and corrosion-resistant construction keep that process straightforward.
No maximum portafilter diameter or bar width is specified for the Rattleware Knock Box. The 6" x 5.5" opening accommodates standard home and prosumer portafilter sizes, but buyers with unusually wide handles should verify fit before purchasing.
