The handle length (excluding bolt stock) is 110mm long and 28mm in diameter at its largest point. It is typically used on commercial Elektra machines as well as their Semi-Automatica version. Note that we consider it too big of a handle for Elektra's LEVA models.
This is one of our favorite handles—not only for its ergonomic feel, but also for its sleek look. It is an original Elektra part, but it can also be used on any portafilter body with a 12mm thread.
