This 51mm Dosing Funnel with 51mm Puck Screen is suitable for 51mm Portafilters. The picture provided indicates that the 51mm Dosing Ring and Puck Screen are only applicable to the 51mm Portafilter.

54/58/58.5mm Portfilters cannot be used. If the inner diameter of your coffee basket is 54mm, 58mm, or 58.5mm, the 51mm Dosing Ring and Puck Screen are not applicable. Please measure the inner diameter of your coffee basket before making a purchase, as this is crucial.

The Dosing Ring material is Aluminum, and it comes with 4 magnets. The Puck Screen material is Stainless Steel. The Espresso Puck Screen 51mm is Reusable with a 1.7mm Thickness and 150μm.

The Puck Screen is easy to take out. After brewing coffee, you can tap the coffee grounds bucket with force, and both the pull screen and coffee grounds will easily fall into the bucket.

Regarding the attraction of the magnets, if your portafilter is Aluminum or Zinc Alloy, the magnet's attraction may not be as good. However, if your portafilter is Stainless Steel, the magnetic attraction will be very good.
