This standard blind basket can be used for backflush cleaning of all machines that have 58mm portafilters, including Gaggia domestic espresso machines that are equipped with a solenoid valve - such as the Classic [NOT RI9403]
Perfect size for my Gaggia. Also use it to stand my tamper in.
Does the job
Backflushed the machine perfectly. Fits nice in the portafilter & group head using the 8mm silicone replacement gasket.
