AKG SA60 Stand Adaptor
Rugged microphone stand adapter to mount microphones with straight or slightly conical diameters of 19 to 27 mm, e.g. AKG C391B, C430, C451B, C451, C480, C568, D112, D190, D40S, D50S, D60S microphones. Jaws hinge on the stand holder at any angle. The stand thread is 5/8 inch and a 3/8 inch thread adaptor is included.
Well, it is what it is. And it's a very good one of them.
Totally overpriced narrow mic clip from AKG to fit their D112 microphone. No alternative though. GAK had the best price I could find for it
