This collar goes straight into the throat of the grinder, allowing for effortless bean retention during operation without a hopper present. The lid inserts snugly inside to prevent pesky popcorning, while still providing an uninterrupted airflow that enhances the functionality of the flexible lens hood mod - a game-changer for effortlessly clearing blockages in the grind chute.
