A27M Thread Size - internal center rod

FAQ #4379 Updated August 29, 2017


What is the thread size of the A27M internal central support rod? I wish to fabricate an adapter that will secure a small digital recorder to the top of the A27M. It will record a back-up to the main recording being done via the two KSM mics on the A27M.


¼ inch, 28 UNF 2A is the male thread of the A27M center rod.
