For many espresso machines, the portafilter is the most handled element in the brewing process. So it's a good idea to have a spare one on hand in case you need a replacement or if you frequently switch between single and double shot filter baskets. This heavy-duty Double Portafilter for Rocket Espresso Machines features a rugged chrome-plated brass construction and a durable plastic handle. Use this portafilter with any single or double shot Rocket 58mm filter basket (not included); fits all Rocket models. Made in Italy.
