Tired of messy espresso pucks? This built-in knock box keeps your counter clean and your workflow smooth. Made from sturdy stainless steel, it's designed to be mounted right into your countertop (you'll need to cut a hole). The bottomless design lets coffee grounds fall directly into a trash can below, saving space and keeping things tidy. The removable rubber knock bar cushions your portafilter, so you get a quiet 'thud' instead of a loud bang – much nicer for home use or early mornings. The rim is also rubber-padded for extra noise reduction. It's easy to clean: just rinse with water or toss it in the dishwasher. Great for home kitchens, cafes, coffee shops, or offices. If you're serious about espresso and want a professional, space-saving way to dump pucks, this knock box is a solid upgrade.
