Grind straight into the cup, then tip it into the portafilter. That's the whole idea — no grounds on the bench, no retention left behind in a chute, and everything you dosed actually ends up in the basket. Stainless steel, sized for 58mm portafilters, and it fits under most lever-arm grinders including the EK43. Cleaner workflow — grind into the cup instead of straight into the portafilter No wasted coffee — everything you dose ends up in the basket Stainless steel — hard-wearing enough for daily commercial service Fits 58mm portafilters Suits most lever-arm grinders, including the EK43 Rounded internal base — grounds don't pack into the corners, so it wipes out easily Short profile — clears low grinder chutes where a taller cup won't fit
