Gaggia Domestic Portafilter Handle This rounded portafilter handle slips over a small rectangular protrusion on the portafilter body and is secured with an Allen head screw (M6 x 12mm hex flange bolt, not included). A removable half-moon insert at the user end gives access to the fixing screw. Used on some Gaggia Baby, Espresso/Dandy, and Coffee models, depending on year of manufacture. COMPATIBILITY Fits: Select Gaggia Baby, Espresso/Dandy, and Coffee models (year-dependent) Replaces: GI_514 Works with: M6 x 12mm hex flange bolt (sold separately) INSTALLATION DIY-friendly, secures with a single Allen head screw. PRO TIPS Confirm your portafilter body has the rectangular protrusion style mount before ordering, some Gaggia handles use a long square shaft instead, and the two styles aren't interchangeable.
