Know before you buy
Yes, the Thor Dosing Ring is specifically engineered for standard 58mm portafilters. Its magnetic base ensures it stays firmly in place during the dosing process.
The magnets are designed solely to secure the ring to the portafilter basket. They are not strong enough to affect the electronics of your scale or the calibration of your grinder.
This ring is designed to be removed after dosing and leveling your grounds. You should remove it before tamping to ensure you can apply even pressure across the entire coffee bed.
The aluminum construction is easy to maintain. Simply wipe it down with a dry cloth or rinse it with warm water and mild soap, ensuring it is completely dry before your next use.
Because the ring is lightweight aluminum, it has minimal thermal mass. It will not significantly draw heat away from your portafilter during the brief time it is attached.
