KNODOS Rosewood Espresso Knock Box V3 — Shock-Absorbent Bar, Removable Liner, Non-Slip Base

KNODOS Rosewood Espresso Knock Box V3

A dedicated knock box built from rosewood for disposing of spent espresso pucks. The rubber knock bar takes the impact, the removable liner catches the grounds, and the non-slip base keeps everything in place while you work. Universal fit — works with any portafilter size.

How It Works

Strike your portafilter against the rubber bar. The spent puck drops into the container below. When the container fills up, lift out the removable liner, empty it, rinse it, and put it back. The process takes a few seconds and keeps your counter clear of loose grounds.

Rubber Knock Bar

The bar runs across the top of the box and absorbs the force of each knock. It is firm enough to release stuck pucks on contact but flexible enough to protect your portafilter basket from dents or scratches. The rubber is food-safe and holds up to repeated daily use without hardening or cracking.

Removable Liner

The inner container lifts straight out of the rosewood frame. Empty it into the compost or trash, rinse it under the tap, and slide it back in. No scrubbing the box itself — the liner keeps the exterior clean.

Non-Slip Base

Rubber feet on the bottom grip the counter surface. The box stays planted when you knock at full force — no chasing it across the counter, no tipping. Works on stone, wood, tile, and laminate surfaces without leaving marks.

Rosewood Construction

Rosewood is darker and denser than walnut, with a deep reddish-brown tone that stands out next to stainless steel machines. The tight grain resists moisture from coffee grounds and cleaning, and the surface develops a deeper color with use. If you are building a rosewood espresso setup with matching KNODOS accessories, this knock box completes the set.

Frequently Asked Questions

What is the difference between the walnut and rosewood knock box?

Same design, same size, same rubber bar and liner. The difference is the wood. Rosewood is darker, denser, and heavier. Walnut is lighter in both color and weight. Both are moisture-resistant and durable. Choose based on which color matches your setup.

How many pucks does this hold?

The container holds enough for a full day of home use — roughly 15–20 pucks depending on dose size. Most home users empty it every 1–2 days.

Will knocking damage my portafilter?

No. The rubber bar absorbs impact and protects the portafilter basket from dents. The bar is designed for repeated use and does not harden over time.

Can I use this with a Breville portafilter?

Yes. The knock box is universal. It works with Breville 54mm portafilters as well as 58mm E61 portafilters and 51mm Delonghi portafilters.

Is this easy to clean?

Yes. The removable liner handles all the mess. Lift it out, empty it, rinse it, put it back. The rosewood exterior just needs a wipe down.
