Knockbox, plastic, black LF L1480768

A knockbox collects spent espresso pucks and loose grounds from portafilters. The barista taps the portafilter against the knock bar, dislodging the compacted coffee into the box below. This keeps the worktop clear and speeds the next extraction by removing the need to scrape each basket by hand.

The knockbox holds the waste until the barista empties it into a bin or compost. Its open top and sloped sides let grounds slide down without sticking, while the knock bar absorbs the impact of repeated taps without damaging the portafilter spouts.

Use is straightforward: place the knockbox on the worktop within reach of the espresso machine. After each shot, knock the portafilter against the bar to release the puck. When the box is full, lift it and tip the contents into the waste stream.

This knockbox is moulded in black plastic, chosen for its resistance to coffee oils and ease of cleaning. The material does not absorb odours or stains, and it withstands the daily knocks of a busy café without cracking or chipping.

The knockbox fits standard portafilters and is sized for countertop use in professional kitchens and coffee stations. Its compact footprint leaves room for other equipment while keeping waste contained and out of sight.

Cleaning is simple: rinse the box under a tap or wipe it with a damp cloth. The smooth plastic surface does not trap grounds, so no scrubbing is needed. For deeper cleaning, the box can be washed in a sink or dishwasher without warping or losing its shape.

The LF knockbox is listed in the barista accessories section of the professional catering catalogue.
