K&M 23510 Microphone Bar, flexible microphone bar for microphone stands, 2 moveable bars position the microphone, each bar is fitted with a captive knurled screw, can be screwed onto all standard microphone stands with a 3/8" threaded connector. Length: 217,00 mm Weight: 0,16 kg
The central section is threaded for a 3/8 microphone boom arm. Nothing wrong with that, but when mating up to a K&M stand the knurled grip ring doesn't fit between the two side arms. Whether it is intended that the grip nut not be used is unclear as there are no specific instructions.
Otherwise, well made (as with all K&M) and a good finish.
