JoeFrex Knock Box

Yes, the knock bar is constructed from aluminum and wrapped in durable, food-safe silicone. It is designed specifically to withstand the repeated impact of knocking out espresso pucks without damaging your portafilter.

Yes, the unit is dishwasher safe. Because the knock bar is fully removable, you can easily clean the container and the bar separately to ensure a thorough wash.

It does. The silicone wrapping on the knock bar acts as a shock absorber, which significantly dampens the loud 'thud' sound typically associated with knocking out coffee grounds.

With a 4-inch diameter and a 4.7-inch height, this knock box has a very compact footprint. It is designed to sit unobtrusively next to your espresso machine without cluttering your workspace.

The Joe Frex Knock Box Basic is designed as a freestanding unit. While it is lightweight due to its duroplastic construction, its compact shape provides enough stability for standard use, though you may want to place it on a non-slip mat if you have a very slick countertop.
