Kupo KCP-628B modular boom arm with KCP-645 and counterweight consists of 3 solid steel columns that can be assembled with a black painted surface treatment. This heavy-duty arm can be fully extended to 2.8 m (6.8 ft) and load up to 6.8 kg (15 lbs). The KCP-645 swivel clamp incorporated in the arm not only offers great flexibility for mounting on the baby pin or junior receiver of the light stand, but also a positive lock with the ratchet handle. The 4 kg (8.8 lbs) KCW-04 counterweight is included and easily increases the stability of the boom thanks to the locking clamp. The steel safety cable is attached to the stand for an additional level of safety while illuminated in the air. The KD-C25P spring clips ensure that the attachment is correct, tight and secure. The T-handle can be used as a tool for mounting/removing the tube.
