The black 23560 Microphone Bar with 5/8" Locking Screws from K&M is a steel bar with six knurled handles for holding microphones. The center of the bar is designed with a 5/8" thread for mounting on a standard microphone stand. Additionally, the bar has six slits; each slit has a knurled screw with a 5/8" thread to attach the microphone, which can be adjusted variably and placed in the desired position on the bar. If six microphones are not used at the same time, the extra knurled screw can be removed from the slits.
