The On-Stage Stands Hex-Base Studio Boom is the new standard by which others will be judged. It is equipped with 2 straight boom shafts for studio, project, or live work. The short boom is removable, while the primary boom arm slides effortlessly through the 1" square housing and locks with a tension knob. Boom angle adjusts with a 40-tooth clutch. The 17 lb patented base is a step above the rest as it provides a low center of gravity, giving it stability even when moved. Includes removable casters.
