The RigWheels RigMount 100 High-Power Magnetic Mount with Short 1/4"-20 Mounting Screw is a magnetic camera car mount made of rare-earth materials to achieve a strong bond. This mount has a short, 1/4"-20 mounting screw on top for use with small cameras, small tripod heads, or support arms.
Each magnet has a special rubber coating to protect the surface you mount on and to prevent slippage, while preserving the pull strength of the magnet. The advantage of a magnetic mount over a suction mount is that it doesn't lose its holding strength over time. The magnets have up to a 100 lb pull resistance when joined together or placed on a steel surface.
The magnet is designed to hold a small-format camera such as a DSLRs or action camera, but you can also use multiple magnets together to support larger rigs. The magnets can also be joined through a glass window or windshield as an additional car mounting option.
