This Kupo KCP-641B Baby Boom telescopic arm with 2 risers and 3 sections, made of durable aluminium, can be used to position reflectors, flash heads, screens, tungsten lights and muslin backdrops. It telescopes from 124 cm to 217 cm and supports up to 5 kg when fully extended. On one side of the Baby Boom telescopic arm there is a 5/8” baby stud, while on the other side there has a hook end that allows hanging a sandbag for added support. The heavy duty tilt locking device is designed to cooperate with a standard grip head to provide the ability to tightly lock and it allows the boom to slide within it to adjust the balance of your load.
