Knock Out Waste Tube DS86L

The DS86L is a knock-out waste tube for a barista bench — the floor-standing bin a barista knocks spent pucks into. It has a durable acrylic knock bar, a removable top for emptying and cleaning, and a secure base plate so it stays put when it is struck. It takes a 230 mm square footprint, stands 900 mm tall and weighs 4 kg. Plastic waste bags and a rubber sleeve are available separately.

Why operators choose the DS86L

• The knock bar is the part that matters — a barista strikes it dozens of times an hour. Acrylic takes that impact without denting or ringing, which is why it is specified rather than metal
• Secure base plate for stability — a tube that shifts when struck is a daily irritation and a spill. The base plate is what makes it a fixture rather than a bin
• Removable top — the whole point of the design - lift the top off to empty and clean rather than tipping a full tube
• Takes a waste bag — drop a bag in and the whole puck load lifts out at close. Bags are available separately
• Rubber sleeve available separately — fits to protect the filter basket and dampen the knock. Worth considering if your bench is near seated customers - the noise of knocking out is real
• 900 mm tall - it stands beside the bench, not on it — this is a floor unit at working height, which frees the bench for the machine and the grinder
• 4 kg — light to move for cleaning, heavy enough with the base plate to stay put in use

Specifications

Venue suitability

The DS86L suits cafes, restaurants, hotels and any bar running an espresso machine — it is standard barista bench equipment. At 230 mm square it tucks in beside the machine and takes the puck waste off the bench entirely.

Installation & delivery

Nothing to install — it needs no power and no plumbing. Allow a 230 mm square of floor or under-bench space beside the machine, within comfortable reach of the group head, and check the 900 mm height against your bench overhang. Consider ordering waste bags with it: they turn emptying into lifting a bag out rather than carrying a loaded tube. Our recorded packed dimensions are shorter than the tube itself, so ask our team if you need exact freight dimensions.

Frequently asked questions

Q: What is a knock-out tube for?

Spent coffee pucks. A barista knocks the group handle against the bar to eject the puck, and the tube catches it. Doing that into a bin on the bench means grounds everywhere; doing it into a purpose-built tube at the right height keeps the bench clean and the movement quick.

Q: Why acrylic for the knock bar?

Impact and noise. The bar is struck dozens of times an hour, so it needs to take repeated blows without denting, and acrylic does that with less ring than metal. It is a genuine specification choice, not a cost saving.

Q: Do I need the waste bags or the rubber sleeve?

Neither is included and neither is essential, but both are useful. Bags mean you lift the waste out rather than carrying a loaded tube to the bin. The rubber sleeve dampens the knock and protects the filter basket - worth it if the bench is close to seated customers, because knocking out is louder than most people expect.

Q: How tall is it and where does it go?

900 mm tall in a 230 mm square footprint, so it stands on the floor beside the machine at working height rather than sitting on the bench. Check it against any bench overhang before you commit the position.

Q: Where is it made?

We are not going to answer that, because our own records contradict each other on it - one field says China and the product description says Australia. Rather than repeat either claim we have flagged it internally for correction. If the country of manufacture matters to your purchase, ask our team and they will confirm with the supplier.

Q: What warranty does the DS86L come with?

Covered for 1 year on a return-to-base basis — the unit goes back for service rather than a technician attending site. Terms vary by product — see our warranty information page for full details.
