The Joby Suction Cup & Locking Arm mounts your action camera on flat, non-porous surfaces using an
industrial strength suction cup that locks in place with a simple
quarter turn of its base. Attached to the Suction Cup is a Locking Arm that lets you position your
camera at any angle thanks to two ball joints that rotate 360° and
pivot 180° from side to side. The arm locks in place with a tightening
knob that won't come loose from vibration. A 1/4"-20 screw at the end of
the Locking Arm lets you attach your camera, or a GoPro tripod mount
for use with GoPro cameras.
