This custom made E61 portafilter is much heavier than most portafilters that come standard with E61 machines; it weighs approximately 23 ounces, which is about 6 ounces heavier than most. This portafilter does not come with an insert basket. An insert basket will be needed to be purchased separately. This portafilter works on all machines with an E61 group (58mm), and the Quick Mill Silvano. When ordering an insert basket for this portafilter be advised it will accept baskets 20 grams or smaller! This portafilter comes with a double spout. If you want it with a single spout we will be happy to change it for you, simply specify in the comment section you would like it with a single spout.
