This funnel adapter is designed to be used with Strietman portafilters. Place it on top and twist it to lock into place. Now you can use your Strietman portafilter on any grinder setup to accept 58mm portafilters. 58mm funnels also fit on top if needed to get closer to your grinder's spout.
You can tamp through before removing the adapter.
