Removal of 1/2 inch and 1/4 inch Flush-mount Microphones
Once mounted, a flush-mount microphone can be difficult to remove. The G.R.A.S. RA0302
Removal Tool for 1/2 inch and 1/4 inch flush-mount microphones makes it possible to remove
the microphone without damage to structure, microphone housing or cable. The removal tool
holds the microphone housing with 8 claws, tightened and loosened by turning a knob, see Fig. 5.
