Brew, knock, repeat The three words embossed on the knock bar sum up the espresso routine. Pull your shot, knock the spent coffee puck from the portafilter, then dose and go again. Cushioned, removable knock bar Strike the portafilter against the silicone knock bar to release the spent puck cleanly into the box. The cushioned surface helps absorb impact and reduce noise. The bar itself lifts out completely for easy emptying and cleaning. Non-slip base A non-slip base keeps the knock box firmly planted on the worktop as you knock out each puck. It also helps dampen the impact and reduce noise during your espresso routine. Angled opening The angled opening gives you plenty of room to knock out the portafilter while helping direct spent pucks and stray grounds into the box, rather than onto the worktop. Powder-coated steel The steel body is made for a permanent place beside your espresso machine. Durable, easy to wipe clean and well suited to the inevitable coffee grounds, drips and daily knocks of a busy coffee station. | Cooks Professional Steel Espresso Knock Box - Coffee Grounds Bin in Black
