What customers say
Customers overwhelmingly praise the MHW-3BOMBER Espresso Knock Box for its superior build quality and stability.

Know before you buy
Select the 51-54mm size if you are using a standard home machine like a DeLonghi or Breville. Choose the 58mm size if you are using a professional-style machine, such as an E61 group head or a La Marzocco.
The knock box is designed to be compatible with a wide range of popular machines, including Breville, La Marzocco, E61, Barsetto, Welhome, and DeLonghi. It functions independently of the machine, so as long as your portafilter size matches the selected model, it will work with your setup.
Yes, the unit is designed with stability in mind. Its durable construction includes a base that stays firmly in place on your countertop while you knock out your espresso pucks.
The knock box is designed for easy maintenance. You can simply empty the used grounds into your compost or trash and wipe the interior with a damp cloth to keep your coffee station clean.
Absolutely. By providing a dedicated, contained space to dispose of your spent grounds, it prevents coffee debris from scattering across your counter, significantly streamlining your post-shot cleanup.
