Ultralight Adjustable Double Ball Arm

The Ultralight DB-EXT is an adjustable double ball arm designed for underwater and cinema camera rigs. Featuring 1" ball ends and a sliding center section, it allows for precise positioning of lights, strobes, monitors, and other accessories. It's ideal for building flexible, custom mounting setups. It adjusts from 12 1/2" to 19" measured from O-ring to O-ring or 13 1/2" to 20" for total length. The ball at each end is our BA-TT mounted to two flat bars with a long 1/4" slot. Each flat bar has one 1/4" threaded hole and each ball end has one 1/4" hole. There is a large round plastic knob that can be tightened or loosened for easy adjustment. It's black in color, made out of 6061 T6 aircraft-grade aluminum with Type III and the hardware is 316 stainless steel.
