We've bundled so you can save! This new kit includes the High Volume Knock Box + EP Trash Can. The ingenious knockbox fits right over the top of our 23 Gallon Plastic Space Saver Trash Can and will allow you to knock out those grounds in massive quantities. Our Barista Basics Knockboxes were designed with quality and durability in mind. Unmatched by any other knockbox on the market, they are made with ultra strong ABS plastic and include a removable NBR rubber knock bar. The removable knock bar and sleek ABS design make these units easy to clean. Backed by the Espresso Parts Warranty and 365 Return Policy, these are built to last!
