This espresso machine portafilter wall mount is designed to fit portafilters that are around 70mm (75mm on V3) wide. The V2 model is tight, while the V3 is larger and should also fit most people due to its sloped surface. Be sure to test if you need to mount the bracket at a slight angle so the handle is perfectly straight when secured.
