Rattleware Knock Boxes

These stainless-steel knock boxes are the ideal solution for removing used coffee grounds from your portafilter, and can be used either as stand-alone units or mounted in-counter.

A replaceable rubber bar cover reduces damage to your portafilter and eliminates the risk of losing the filter to the garbage disposal and increases safety with handling.

Made with sturdy 18/8 stainless steel. Features a welded metal bar for strong sides.

Choose from a variety of finishes and shapes.

Note: All options – except the basic square – come with a protective edge gasket made of molded rubber.

The various finishes (Powdercoated Steel, Maple and Stainless Steel) add strength to your knockbox.
