The Avenger C339BB Grab Clamp with Baby Bushing is flexible and fast and thanks to its pincer jaw design can be affixed to a wider variety of round or square pipes, beams and bars than traditional clamps. It has a push button lock for extra safety and a standard 5/8″ Baby receiver for fixtures and gear with a matching stud. Used in TV, video and photographic studios and theaters, the Grab Clamp will hold up to 50kg (110lb).
