Joe Frex KBS – Portafilter Knock Box Black

The Joe Frex KBS is a black portafilter knock box made of ABS plastic, rubber and stainless steel. A knock box is an essential item next to every espresso machine. The KBS measures 10cm across and 12cm tall including the base, weighs 448g, and its black finish suits any kitchen or bar.

Features

• Fixed stainless steel bar covered with rubber
• The rubber covering reduces noise and protects the portafilter
• Silicone ring on the base for stability and to protect the counter
• Materials: ABS, silicone, rubber, stainless steel
• Dimensions: diameter 10cm x height 12cm

How to use it

Straight after extraction, knock the portafilter against the bar with a firm, short movement so the coffee puck drops out whole. Strike with the rim of the portafilter, not the basket or the handle. Empty the box before it fills up to the bar, so grounds do not pile up.

Care

Empty and rinse the box regularly, at least at the end of each day, and let it dry. Wet coffee grounds left for hours cause odours.
