An essential barista tool for anyone making espresso, this stainless steel coffee knock box is an ideal way to collect spent espresso grounds from your machine's filter basket. The 6" deep stainless steel "box" fits into any 1/6 size opening and is large enough to hold spent coffee grounds from multiple drink orders, sparing your staff from constant trips to the trash can or sink to dispose of grounds, and from potentially cross contaminating the filter. The rubber-wrapped knock bar makes it easy to "knock out" spent espresso grounds, and the corrosion-resistant 23-gauge stainless steel box is easy to empty and clean. The espresso knock box measures 7" x 6" x 5."
