Anyway, this is a four spoked distribution tool which finds the level of the coffee in the basket with gravity, not a lot to say about it, which why I'm waffling about Isaac Newton.
Features and Benefits:
• Four spoked distribution tool
• 304 stainless steel spokes
• Aluminium outer
• Size: Available for portafilter sizes 49, 51, 54 & 58mm
• Gravity levelling
The idea of gravity fed distribution tools is that they'll automatically find the level, rather than using a fixed depth, which removes the trial and error involved in finding the right level using a fixed depth tool.
So, yeah, there you go, this is a gravity fed distribution tool available in black or silver, for 49, 51, 54 & 58mm portafilters.
