The Foba CIBAU Articulated Arm Set for Combitube System is part of the Combitube System. It is the lighter version of Foba's articulated arms, designed for light loads and less exacting applications. The three joints of the arm are locked simultaneously by turning a single knob. Make use of the CIBAK Clamp to hold props, reflectors or other items on your set. The CIBAF 6" (15cm) diameter base supports it all.
