The Telescopic Support Arm is a Manfrotto 233B Camera Mount Bracket (without the Manfrotto 143BKT camera plate). There is a cup at the extremity of the arm, providing a large surface of contact. The cup has a 4" (10 cm) diameter. The arm can be extended from 14" (36 cm) to 20" (51 cm). The arm can be placed everywhere around you, by rotating it on 360 degrees horizontally and vertically.
Simply place the cup on a stable surface. It can rest on your waist, your hip or your thigh. It can rests on the ground or a nearby wall for more stability. The cup can be quickly removed. The telescopic arm can then support accessories like a microphone or a camera light. The Telescopic Support Arm adds stability and versatility to the camera support.
