A silver dosing ring for 58 mm portafilters
Set it on a 58 mm portafilter, grind into it, and the sloped inner wall guides the grounds down into the basket. It is aluminum alloy, with a ring weight of about 1.8–2.1 oz (50–60 g). This is the plain ring with no magnets; one ring per order, no tamper included.
While you grind
Grounds land inside the ring
The ring raises the edge above the basket, so grounds that fall toward the edge land inside the ring rather than on the counter. Lift the ring off before you tamp.
Before you order
Check your basket size
This ring is made for 58 mm (2.28 in) portafilters only. Measure the top of your basket and the space under your grinder first.
