Rhino Coffee Gear Mini Knock Box

The Rhino Coffee Gear Mini Knock Box is a compact, well-built espresso knock box designed for home coffee setups where counter space is limited. At just 100mm tall and 110mm in diameter, it fits neatly beside any home espresso machine and holds around six spent pucks before needing to be emptied — enough for a full session without interrupting your workflow.

Built for Easy Use and Fast Cleanup

A removable, hard-wearing rubber knock bar sits across the top of the bin, giving you a firm surface to knock your portafilter against to release the spent puck. The rubber base grips the counter firmly, keeping the bin stable even during repeated knocking. When it's time to clean up, the body is dishwasher safe — just remove the rubber bar first and hand wash it separately. Alternatively, a quick rinse under running water does the job just as well between sessions.

Small Footprint, Practical Capacity

At 100mm (h) x 110mm (diameter), the Mini Knock Box takes up minimal counter space while still providing enough room for regular home espresso use. Its cylindrical shape keeps it unobtrusive on the bench, and the clean lines mean it sits comfortably alongside grinders, tampers, and espresso machines without looking out of place.

Available in Three Colours

The Mini Knock Box is available in Black, White, and Grey, making it easy to match your existing coffee station setup or kitchen aesthetic.

Frequently Asked Questions

What is a knock box used for?

A knock box is used to dispose of spent espresso pucks after pulling a shot. After brewing, the used coffee grounds remain compressed inside the portafilter basket. You knock the portafilter firmly against the rubber bar of the knock box, which dislodges the puck cleanly into the bin below. It keeps spent grounds contained and your counter clean, and is much more practical than knocking the portafilter against a bin or the edge of a counter.

How many pucks does the Rhino Mini Knock Box hold?

It holds approximately six spent espresso pucks before needing to be emptied — sufficient for most home espresso sessions. For households pulling a larger number of shots daily, it's simply a case of emptying it more frequently, which takes only a few seconds.

What are the dimensions?

The Mini Knock Box is 100mm tall with a diameter of 110mm (approximately 4" x 4.3"). This compact footprint makes it well suited to home espresso setups where bench space is at a premium.

Is it dishwasher safe?

Yes — the body of the knock box is dishwasher safe. The rubber knock bar should be removed before putting it in the dishwasher and washed by hand separately. The bin can also be rinsed quickly under running water after each use if preferred.

Does the bin stay in place when knocking?

Yes. The rubber base grips the counter surface firmly, preventing the bin from sliding during use, even with repeated firm knocking.

What colours are available?

The Rhino Coffee Gear Mini Knock Box is available in Black, White, and Grey.
