Ultimate Support JS-FB100 Fixed-Length Microphone Boom Arm

The Ultimate Support JS-FB100 is built for working musicians, engineers, and production crews who need a reliable boom arm without the bulk or cost of a full stand replacement. Whether on a rehearsal stage, in a project studio, or at a live event, the JS-FB100 threads directly onto any existing microphone stand and delivers a fixed boom position that stays put through repeated setups and teardowns.

The all-metal housing is powder coated for scratch resistance, making it a practical choice for touring and club environments where gear takes a beating. The comfortable adjustment dial and knob allow quick repositioning of the mic angle, while the included cable management clip keeps signal cables routed cleanly. Standard 5/8-inch threading ensures compatibility across virtually all mic stand brands and makes this arm a go-to add-on for engineers building out a mic locker without replacing existing hardware.

Unlike plastic or hybrid boom arms that flex under dynamic microphone weight, the JS-FB100 uses metal telescoping construction throughout, providing the rigidity and longevity that production and install teams depend on. Its straightforward design means no tools, no adapters, and no wasted time at setup.
