The On-Stage MSA7020B is a top-mounted boom arm for your microphone stand. This non-telescoping boom gives you 32" of range and features standard 5/8"-27 threads, as well as a positioning washer, plastic end caps on its T-knob, a counterweight, and stamped rubber pads. These pads provide a solid, reliable grip. The rotation of this boom is 360°, which facilitates flexibility in the mic-positioning process. It is fashioned out of steel—a solid metal indeed.
