Use the Zuma B Series Junior Boom Arm to mount overhead lights to a standard 5/8' light stand and properly expose your studio production or film footage. Two sections extend up to 7' long and can withstand loads up to 22 lb. The arm has a junior 1-1/8' receiver on one end and a hook at the other to attach the included empty sandbag, which can be filled to an optimal counterbalance weight.
