Constructed from three assembled solid steel columns, this heavy-duty boom arm can be fully extended to 9.2ft (2.8m), and support loads up to 15lbs (6.8kg). The built-in pivoting boom arm clamp not only offers great flexibility to be mounted on the baby stud or junior receiver on the light stand, but also a lock with the ratcheted handle. The 10lb (4.5kg) wrap & go shot bag is included and allows you to increase the stability of the boom by just wrapping it around. The steel safety wire is attached to the stand for an extra level of security. Can easily be disassembled to 32 (93cm) for storage or transport.
