Rhino Coffee Gear Thumpa Floor Standing Knock Tube

The Rhino Coffee Gear Thumpa is the go-to floor standing knock tube for high-volume commercial cafés. Standing 860mm tall and built from high-density, shock-resistant polyethylene (HDPE), it was designed from the ground up to handle everything a busy espresso bar throws at it — repeated impacts, heavy daily use, and the kind of treatment that would destroy a standard knock box. It sits on the floor beside the espresso machine, keeping the entire counter surface clear while giving baristas an always-accessible point to knock out spent pucks throughout service.

Virtually Indestructible

The Thumpa's HDPE construction absorbs shocks that would crack or deform lesser materials — it can be hit, knocked, bashed, and dropped without coming apart. Commercial coffee waste solutions need to withstand this kind of punishment across hundreds of shots a day, and the Thumpa is built specifically for that environment. The flared collar at the top also catches any excess splatter during knocking, keeping the surrounding floor clean.

Designed for Easy Maintenance

The slotted knock bar inserts and removes easily for cleaning, replacement, or maintenance — no tools needed. The top of the tube is fully removable for emptying, or the Thumpa can be used with a standard waste bag liner for even faster changeovers during service. Every single component is replaceable individually, meaning the tube itself has an indefinite working lifespan with routine upkeep.

Adaptable to Your Setup

The Thumpa can be cut down to a shorter height if your setup requires it — useful where a full 860mm height isn't practical. This makes it adaptable to a wider range of bar configurations without needing a separate product. A shorter 300mm bench-top version is also available for setups that need something more compact.

Frequently Asked Questions

What is the Rhino Thumpa and how does it work?

The Rhino Thumpa is a floor standing knock tube designed for commercial espresso bars. It stands on the floor beside the espresso machine, and baristas knock their portafilter against the internal slotted bar to release the spent puck, which drops into the tube below. The large 860mm height provides substantial capacity before the tube needs to be emptied, and the removable top means it can be lined with a waste bag for even faster changeovers during busy service.

What material is the Thumpa made from?

The Thumpa is made from high-density, shock-resistant polyethylene (HDPE) — a material chosen specifically for its ability to absorb repeated impacts without cracking or deforming. Unlike stainless steel knock boxes, the HDPE construction also means the tube is lighter and less likely to damage the portafilter or surrounding equipment if knocked over.

How tall is the Thumpa and can it be cut down?

The Thumpa stands 860mm (approximately 34") tall. It can be cut down to a shorter height if your bar layout requires it — the tube construction allows this without compromising the structural integrity of the unit. A separate 300mm bench-top version is also available for setups where a floor standing tube isn't practical.

Is the knock bar replaceable?

Yes. The slotted knock bar inserts and removes easily without tools, making it simple to clean, maintain, or replace. Every component of the Thumpa is available as a replacement part, which means the tube can be kept in service indefinitely with routine maintenance rather than being replaced as a whole unit.

Can it be used with a waste bag?

Yes. The removable top means a standard waste bag can be fitted inside the tube for liner-style disposal. This is particularly useful during busy service where fast changeovers between empties are needed — the full bag can be lifted out and replaced in seconds.

Is it suitable for home use?

The Thumpa is designed and sized for commercial café environments. At 860mm tall it is a substantial piece of equipment better suited to a commercial bar than a home kitchen. For home espresso setups, the Rhino Mini Knock Box or standard Rhino Knock Box are more appropriate options.
