Rhino Coffee Gear Knock Box

The Rhino Coffee Gear Knock Box is a practical, well-sized knock box designed for home espresso setups and light office use. At 150mm tall and 140mm in diameter, it holds approximately 20 spent espresso pucks before needing to be emptied — enough for a full day of home brewing without interruption — and sits neatly on the counter beside your espresso machine without taking up too much space.

Quiet, Stable, Easy to Use

The rubber-coated knock bar absorbs impact during use, keeping noise to a minimum when knocking out spent pucks — a genuine consideration if you're pulling shots early in the morning. The non-slip rubber base holds the knock box firmly in place on smooth counter surfaces, so it stays put even with repeated firm knocking. The plastic body is straightforward to rinse out or wipe clean after use.

The Right Size for Home Use

Where the Rhino Mini Knock Box is sized for very compact setups (around 6 pucks), this model steps up to around 20 pucks capacity — better suited to households pulling multiple shots daily, or anyone who prefers emptying less frequently. At 150mm x 140mm it still has a modest footprint that fits comfortably in a typical home kitchen setup.

Built by Rhino Coffee Gear

Rhino Coffee Gear is trusted by both home baristas and professional café environments worldwide. Their knock box range is built to handle the repetitive daily impact of espresso puck disposal while remaining practical and low-maintenance.

Frequently Asked Questions

How many pucks does this knock box hold?

The Rhino Coffee Gear Knock Box holds approximately 20 spent espresso pucks. This makes it well suited to home setups where multiple shots are pulled throughout the day, as it can typically go a full day or more between empties depending on your usage.

What is the difference between this and the Rhino Mini Knock Box?

The main difference is size and capacity. The Mini Knock Box measures 100mm x 110mm and holds around 6 pucks — ideal for very compact setups or low-volume use. This model is 150mm x 140mm with approximately 20 puck capacity, making it the better choice for households that pull several shots a day or simply prefer emptying less often.

What is the knock bar made from?

The knock bar is rubber-coated, which serves two purposes: it cushions the impact of the portafilter to protect the basket rim, and it dampens the sound of knocking — making operation noticeably quieter than metal knock bars.

Does the base grip the counter?

Yes. The rubber base holds the knock box firmly on smooth surfaces, preventing it from sliding during use even with repeated firm knocking.

How do you clean it?

The plastic body can be rinsed under running water or wiped out with a damp cloth. For a more thorough clean, remove the knock bar before washing. The compact, open design makes it quick to clean and dry.

Is it suitable for café use?

It is designed primarily for home and light office use. For high-volume café environments pulling a large number of shots throughout the day, the Rhino Deluxe Knock Box or a commercial knock chute would be more appropriate.
