SmallRig 4467 Overview
The Dual Magnetic Suction Cup with Magic Arm Mounting Support Kit from SmallRig attaches action cameras to flat, metal surfaces using two durable suction cups with combination magnetic mounts, and on top is an adjustable magic arm. The mount is designed to be used with moving vehicles going less than 74 mph. This is particularly useful for vloggers, reality television productions, and other low-impact applications.
 
Action cameras equipped with a standard three-prong mounting platform are fastened to an included adapter, which sports a 1/4"-20 threaded receiver. This screws into the dual ball magic arm that is integrated into a bar connecting the suction cups, providing nearly 360° of pan, tilt, and roll. A simple push allows action cameras of up to 12.3 oz to be securely attached to clean, flat surfaces. The integrated magnets provide added security on metal surfaces such as aluminum, iron, or steel.
 
The mount does not include a safety tether, so a separately available safety tether is highly recommended when using it on vehicles at high speed. It is not for use on glass, carbon fiber, special alloy metal, painted surfaces, marble, textured wallpaper, diatom mud walls, unpainted wood, frosted glass, and other rough or textured surfaces.
 
Usage Notes
The package does not include a safety tether, so use a separately available tether when using at high speed. It is recommended to keep the speed below 74mph and check the suction force before use and every hour.
