The Modus Camera Mounting System with Case from ProAm USA is the foundation of a professional camera mounting system for use on vehicles and dolly tracks. The system is recommended to support cameras and accessories up to 12 lb. Features include various 1/4"-20 and 3/8"-16 threads for optional plates and tripod heads, rubber coating to prevent scratching, and four magnet mounts with 40 lb of vertical pull strength per magnet.
While the vertical pulling strength maxes at 40 lb, real-world conditions reduce the operating weight limit. Mounted loads will put additional torque on the magnet. Camera and accessories, when mounted, raise the center of gravity of the mount, making it easier to remove.
Note:
Always use a secondary method of securing the device being mounted, such as a lanyard or tie-down strap.
