What customers say
This premium marble knock box is celebrated for its stunning aesthetic and superior stability. Its substantial weight is the greatest functional advantage, ensuring it remains firmly in place during use, unlike lighter alternatives. Reviewers frequently describe the luxurious marble finish as art, justifying its prominent display. The durable surface simplifies cleanup and promises longevity. While the quality is undeniable, the high price point is the main consideration, positioning it as a luxury investment rather than a necessity. Serious home baristas value this fixture for its perfect blend of sophisticated form and reliable function.
Know before you buy
Because it is natural stone, you should wipe it down with a damp cloth after use to prevent coffee oils from staining the surface. Avoid using harsh chemical cleaners that could etch or dull the polished marble finish.
The knock bar is wrapped in aluminum-reinforced silicone, which effectively dampens the sound of the portafilter hitting the bar. While it is not silent, it is significantly quieter than a hard plastic or metal-on-metal knock box.
Yes, the knock bar is designed to be removed, allowing you to easily empty the grounds and clean the interior of the marble basin. We recommend hand-washing the bar to preserve the integrity of the silicone coating.
At nearly 3.3 kilograms, this unit is exceptionally heavy and stable. It is designed to stay firmly in place on your counter, even when you are knocking out stubborn espresso pucks with force.
Yes, the 5.8-inch height is well-suited for standard portafilters, including bottomless versions. The open design allows for easy clearance when you are knocking out grounds.
