Hand Made Wood Portafilter Handle - Walnut. Portafilter bodies are not included in the price of this product. Will it fit? The 10mm O.D. threaded bolt does not fit the large majority of the manufacturers out there, except for Carimali, La Cimbali, (Marzocco plastic handle version bodies) Nuova Simonelli, Rancilio (aftermarket) and La San Marco (and other manufactures that are more obscure). One may want to remove their existing handle and check the size first. 10mm = 0.393 or approximately 13/32 of an inch. Remember, not all manufactures handles simply unthread from the body; some are held in place with a nut and washer. The handle may be held to the body with thread-lock on the bolt as well. In most cases, a vice is needed to remove the handle.
