AtlasIED PB21XEB Extendable Boom Arm With Counterweight | Ebony

The AtlasIED PB21XEB is a replacement and add-on boom arm designed for production engineers, installers, and touring crews who need reliable extendable reach for miking applications. Its single-motion extension mechanism allows fast, tool-free adjustment on stage or in the field without repositioning the entire stand assembly.

The fixed 2 lb counterweight keeps the arm balanced across its extension range, reducing the risk of tip-over during live sound events or installed audio setups where consistent positioning is critical. The threaded end cap provides compatibility with standard mic stand hardware, making it straightforward to integrate into existing AtlasIED stand systems.

Finished in ebony epoxy, this boom arm suits installs where a darker, unobtrusive aesthetic is required — theater environments, black-box performance spaces, and house-of-worship installations where gear visibility is a factor. Sold as boom arm only; tube assembly is purchased separately, giving integrators the flexibility to pair it with the appropriate stand for each application.
