SmallRig 4467 double magnetic suction cup mounting kit for action cameras It is recommended for use only on flat iron surfaces such as iron doors, railings, kitchen utensils, sports equipment, etc. Even in the unlikely event that the silicone suction cup leaks due to strong vibrations, the magnets can pull the entire mounting support to the surface of the iron car (within the limit of a load capacity of 0,35 kg in a dynamic shooting scene on a flat road, when the maximum speed does not exceed 120 km/h), effectively avoiding the risk of falling due to leakage of the silicone suction cup. A 1/4"-20 screw at one end allows attachment of an action camera, monitor, LED video light, microphone, etc., and built-in rubber pins support SmallRig 3084, 3083, 4088, 4119 and other accessories with locating holes to prevent flexing.
