Overview

The K&M 21110.500.55 is a classic two-piece telescopic boom arm designed to pair with any microphone stand that has a standard 5/8" threaded connector. Extending from 17 to 29 inches, it provides enough reach to position microphones precisely over drum kits, in front of amplifiers, or at comfortable angles for vocalists and podcasters. The T-Bar locking system ensures a secure attachment to the stand, while the wing nut allows quick length adjustments on the fly. At just one pound, it adds negligible weight to the top of a stand, helping maintain stability.

Built in Germany, the 21110 reflects K&M's seven decades of expertise in stand and mount design. The swivel joint is engineered for smooth, silent, and scratch-free repositioning—an important detail in recording environments where any mechanical noise can bleed into a take. The alloy steel construction stands up to the demands of touring, studio work, and rehearsal use alike. K&M backs it with a 5-year warranty and commits to keeping replacement parts available for 10 years, making it a long-term investment rather than a disposable accessory. The company's ISO-14001 environmental certification also means the manufacturing process meets recognized sustainability standards.
