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

The KNODOS Walnut Espresso Knock Box V3 is a standalone knock box built from solid American walnut for disposing of spent espresso pucks. Strike your portafilter against the shock-absorbent rubber bar, the puck drops into the removable liner, and the non-slip base keeps the box planted on your counter. The warm walnut tone matches other KNODOS walnut accessories for a coordinated setup. Universal fit — works with any portafilter size including 51mm, 54mm, and 58mm.

Shock-Absorbent Knock Bar

The rubber knock bar runs across the center of the box. Hit the portafilter against it to dislodge the spent puck — the rubber absorbs the impact so you can knock hard without damaging the portafilter basket or the box itself. The bar is firm enough to release even tightly packed pucks on the first strike.

Removable Interior for Easy Cleaning

The inside liner lifts out for emptying and cleaning. Dump the grounds, rinse the liner, and drop it back in. The box stays on the counter — no need to move the entire unit to the sink after every session.

Non-Slip Base

The bottom of the box grips the counter so it stays in place when you knock. No suction cups, no adhesive — the base material provides enough friction to keep the box planted during normal use, even on smooth stone or tile countertops.

American Walnut Construction

Built from solid American walnut — the same wood used across the KNODOS walnut tamper, distributor, and tamping station lineup. The warm brown tone looks consistent next to any espresso machine and ages well with daily use. Walnut is naturally moisture-resistant, so the exterior handles exposure to steam, coffee grounds, and water without warping or staining.

How to Use — Step by Step

1. Place the knock box on a flat countertop next to your espresso machine.

2. After pulling a shot, hold the portafilter over the knock box.

3. Strike the portafilter firmly against the rubber knock bar.

4. The spent puck drops into the removable liner below.

5. When the liner fills up, lift it out, empty the grounds, rinse, and replace.
