The Model 7 Boom is a quiet, smooth and easy to use telescopic    Microphone Boom with a variety of features and accessories that enable    operators to position microphones in nearly any position. This Boom is    primarily for use in television production and has provided the industry    with a long history of reliable service. The Model 7 Boom is available in    four different lengths, providing sound personnel with a wide range of    flexibility. The Model 7 Boom can be mounted overhead on Catwalk    Stands (ACS, CS) or on stage flooring using the Model 6 Base (6).    A new feature available on our longer Booms is a Carbon Fiber inside    tube that is lighter, more rigid and quieter than standard tubes.    The Carbon Fiber inside tube is standard on the 29-Foot Boom and    optional on the 26-Foot Boom.
