The Rattleware Stainless Steel Knock Box is a heavy-duty espresso grounds disposal box measuring 9.25 inches by 5.5 inches by 4 inches, built for daily use at home espresso stations and commercial bars. The stainless steel body, rubber gasket, and integrated splash guard work together to keep the disposal process contained and surfaces clean.
The Rattleware Knock Box is constructed from heavy-duty stainless steel, a material that resists corrosion, holds up to repeated impacts from a portafilter bar, and cleans easily between sessions. For a barista pulling multiple shots a day, that durability means the box stays functional and presentable without warping, cracking, or developing the odors that plastic alternatives can accumulate over time.
The rubber gasket seals the base of the knock bar and absorbs impact, reducing the sharp crack that comes with knocking out a spent puck. The splash guard catches stray grounds and moisture that would otherwise scatter across the counter. Together, these two features make the disposal step faster to clean up after, which matters most during a busy service window or a home setup where counter space doubles as a workspace.
At 9.25 inches by 5.5 inches by 4 inches, the Rattleware Knock Box occupies a small, defined rectangle on the counter rather than crowding the area around the espresso machine. The proportions are sized to accept a standard portafilter knock without tipping, while leaving room for a grinder, tamper mat, and pitcher on a typical home or commercial bar setup.

The Rattleware Knock Box suits home baristas and commercial bar setups that pull espresso daily and need a durable, low-maintenance grounds disposal solution. The stainless steel construction and splash guard make it a practical fit for any station where cleanliness and longevity matter.
This knock box is not designed for drip or pour-over coffee workflows, which do not use a portafilter. It is a single fixed size and does not expand or collapse for storage.
The Rattleware Knock Box measures 9.25 inches long by 5.5 inches wide by 4 inches tall. That footprint is compact enough for most home espresso stations and commercial bar setups where counter space is shared with a grinder and other tools. It sits on the counter rather than mounting beneath equipment.
The rubber gasket on the Rattleware Knock Box is positioned to absorb the impact of the portafilter against the knock bar. This dampens the sharp crack that an unpadded metal bar produces, which is a practical benefit in a quiet home kitchen or a customer-facing café environment.
The Rattleware Knock Box is built for both commercial and home use. The heavy-duty stainless steel construction is intended to handle the volume and repeated impact of a commercial espresso bar, while the compact 9.25" x 5.5" x 4" footprint also suits a home setup.
