This is a single Dosing Ring 58mm Silver. We also have black, 51mm, and 53mm sizes in stock, so please inquire. The third image shows 51mm/53mm/58mm from the right. This is a dosing ring (funnel) for espresso. It is placed on top of the portafilter to make it easier to catch the grounds coming from the grinder, effectively preventing coffee powder from scattering. Magnets are embedded in the ring, allowing it to adhere to metal filters and not easily fall off. This 58mm bottom diameter is for espresso machines with a 58mm filter diameter, such as the standard E61 group head for commercial use, but please confirm compatibility before purchasing. The item is new and unused, but please refrain from purchasing if you are sensitive to this or are looking for unopened, new products. 【Specifications】 Material: Aluminum, Magnet 58Φ Size/Weight: Outer diameter: 70mm / Ring outer diameter: 58mm / Overall height: 22mm / Weight: 41g (Reference) 51Φ Size/Weight: Outer diameter: 62mm / Ring outer diameter: 51mm / Overall height: 22mm / Weight: 34g 53Φ Size/Weight: Outer diameter: 64mm / Ring outer diameter: 53mm / Overall height: 22mm / Weight: 37g Shipping costs will be discounted only when combined with other items.
