JoeFrex Knock Box

The wood housing is designed for durability, but it is not waterproof. We recommend wiping away any coffee spills or moisture immediately to maintain the finish and prevent the wood from warping over time.

No, the Joe Frex Knock Box Classic is not dishwasher safe. The internal PVC container is removable, so you can easily rinse it by hand, but the wooden housing should only be cleaned with a damp cloth.

The internal PVC container lifts right out of the wooden housing. Simply remove it, dump the spent grounds, and rinse it under warm water with a mild detergent before drying it completely.

The design is minimalist and relies on the weight of the wood housing to stay in place. While it doesn't feature a rubberized bottom, the solid construction provides enough stability for standard knocking motions on most countertop surfaces.

The unit measures 5.5 inches in height, width, and depth. It is compact enough to sit beside most home espresso machines, but you should measure your specific clearance if you plan to tuck it underneath a low-profile setup.
