Coffee Knock Box - Black - 4.9"

A coffee knock box is used to collect and easily dispose of used espresso grounds (coffee pucks) from your portafilter, minimizing mess around your coffee machine.

Detach the bar, empty the grounds, and then wash both the box and bar with warm, soapy water. Rinse and dry thoroughly. It is not dishwasher safe.

Yes, the bar is designed to be detachable, making it easy to empty grounds and clean both the bar and the interior of the knock box.

The knock box is constructed from durable ABS plastic with a silicone non-slip base and a rubber bar.

This specific model has a diameter of 4.9 inches.

While primarily designed for espresso pucks, it can be used for other coarser coffee grounds, but it may fill up faster and require more frequent emptying.

The plastic construction and rubber bar help to dampen the sound compared to knocking directly into a hard surface, but some noise is expected.

Ensure the surface is clean and dry. Verify that the silicone non-slip base is securely attached and free of debris.

Gently wiggle the bar from side to side while lifting. If new, it may be a snug fit; after a few uses, it will loosen slightly.

Ensure you are knocking the portafilter firmly but not excessively hard. Empty the knock box when it is about two-thirds full to prevent overflow.
