RigWheels Kit 4 is a car suction mount comprised of 1 RigPlate and 4 of industrial strength suction cups. A-Cups are standard but you can also upgrade with B-Cups or C-Cups. This configuration can be used to mount cameras as well as many standard production tools such as lights, flags, clamps and arms onto cars, windows and any other smooth non-porous surfaces. With the 14 tapped holes in RigPlate you'll have the mounting options to be able to place your car suction mount in just the right spot to get the perfect shot.
You will notice 3 different versions of suction cups that RigWheels offer for use in car suction mounts. The included A-Cups are the most general purpose and most cost effective. The B-Cups have more holding power in a straight pull and they have less flex so the overall mount is a bit more solid. The trade off is that the B-Cups are more easily removed so if the mount is going to be subject to a lot of outside forces (wind, water, etc.) than the A or C version is recommended. C-Cups are for the most serious of jobs with a vacuum pump mechanism to keep the suction cup securely affixed to a surface with a visual safety indicator.
