Knock boxes, also known as ‘bash bins’, are valuable pieces of kit for quickly and efficiently disposing of coffee pucks. Because pucks are hot, knock boxes are usually made of stainless steel or moulded plastic and have a sturdy bar that is capable of being bashed repeatedly by the portafilter, and in the process saving baristas the need to find a bin.
For professional baristas where time is of the essence, knock boxes are essential tools. Whether they are freestanding on the floor or the counter, sunk into the countertop or placed under the grinder, their stability, capacity and sturdiness are usually deciding factors when purchasing. Choose from a variety of colours, sizes, materials and types, including stainless steel knock drawers and rubber boxes, plus options for domestic and commercial use. A large selection of replacement spares such as knock bars and sleeves are also available if repairs are needed.
For the home Barista: We suggest countertop knock boxes in rubber or high-quality stainless steel with non-slip rubber bases.
The large Tubbi can comfortably hold 40 double pucks, with the smaller version being able to hold 10 before it needs emptying. A silicone ring on the bottom prevents movement and reduces noise. To empty just lift the rubber bar out and discard.
This large Tubbi features a press fit silicone gasket on the bottom which means you can strip it down and clean it however you want, wash it by hand or put it in the dishwasher. To wash we recommend you just give it a rinse in mild detergent. The plastic tub is dishwasher safe but we are not sure you need to go that far, as a mild rinse works every time.
