This is a fabulous Extra Large (XL) Knockout Box. It is big enough for commercial use yet takes up minimal amount of space near the machine. The body is constructed of stainless steel and it sits inside a heavy non-slip rubber base. The removable rubber-coated bar provides the perfect surface for “knocking out” spent coffee.It provides a convenient, no fuss, no mess way to safely dispose of your coffee grinds. Great for any home OR coffee bar. It also makes an ideal gift for the discerning coffee drinker!
