ECM Knockbox

Yes, the knock bar is specifically engineered to absorb impact, which significantly reduces the sharp, metallic clanging noise typically associated with emptying portafilters.

It is designed with a rubberized base that provides excellent grip, keeping the unit stable and preventing it from sliding or tipping over during forceful knocks.

Cleaning is straightforward because the knock bar is fully removable. You can easily take it out to rinse it or wipe down the stainless steel interior whenever needed.

While the brushed finish is more forgiving than polished chrome, it can still show smudges over time. A quick wipe with a damp cloth is usually all that is required to keep it looking clean.

The round design is compact and ideal for home use, fitting neatly next to most espresso machines without taking up excessive counter space. If you pull a very high volume of shots throughout the day, you may find yourself emptying it more frequently than a larger, commercial-style box.
