Rhinowares Professional Stainless Steel Knock Box

The Professional Stainless Steel Knock Box from Rhinowares has a larger capacity, that is suitable for professional use. The knock box has a diameter of 150 mm, and a height of 165 mm, so it fits a generous amount of coffee grounds.

The knock box has a non-slip silicone base that keeps it steadily in place even when taking a heavy beating. The knock box also has a silicone collar that protects the portafilter when your aim is a bit off.
