If you are tired of having your portafilter basket fall out on you we can machine a groove in your portafilter and install a retention spring to hold the basket snugly in place.  You will still be able to remove it easily, but it won't fall out unintentionally.  Simply purchase this item and we will provide you a mailing address for you to send your portafilter and portafilter basket.  Typically your portafilter will be back to you within less than two weeks.  This service is available for all makes and models.  Please contact us with questions.
