The RigWheels RigMount X6 Magnet Camera Mounting Platform features industrial-grade high-power magnets to secure your camera and other equipment to a steel surface. The magnets are covered in just enough rubber material to prevent scratching of your chosen steel surface without sacrificing holding strength. The mount features many 1/4"-20 and 3/8"-16 threaded mounting holes and its six powerful magnets can securely hold up to 300 pounds (or approximately 50 pounds per magnet).
