Countryman's A2CSM ISOMAX 2 Stage Mount is a small metal plate fitted with an alligator clip used to mount the ISOMAX 2 instrument mic on a floor, table, lectern, or other flat surface. This lets the ISOMAX 2 function almost like a typical boundary mic.
Sticky urethane foam on the bottom of the stage mount helps keep it in place.
