A swan neck style arm that fits onto a Super Clamp. Not stiff enough to hold anything substatial - and almost unable to hold itself with no load. Place it in a certain position, and it will slowly creep to somewhere else. It's basically useless for cameras and will definitely shift if moved or shaken. It can be OK for static work and really light loads like small flashes or reflectors, but nothing heavier. Go for a Manfrotto Friction Arm in stead if you want something flexible that can actually hold stuff.
