This is the free standing, floor standing, knock box tube from Crema pro, the manufacturer previously known as coffee beens.
The tube sits at a height of 860 mm, which is roughly the same height as the average UK standard specification washing machine.
The head of the box is removable and this enables the use of a bag internally for easy removal and disposal of used coffee grounds at the end of every day, ideal for the busy commercial coffee outlet. The box has small vents cut into the lower region of the tube, these prevent a vacuum effect from occurring when the plastic bag is placed inside.
The tube is made of rugged plastic (hard wearing polypropylene) which is easy to wipe clean, it can be separated into 3 separate parts to further enable ease of cleaning.
A clever design and genuinely useful bit of kit the box is both sturdy and capable, it has a strong following by those who have used it.
Spare knock bar rubbers are readily available.
