Serious engineering

Treat your phone like the professional camera that it is. We precisely cut each Beastcage from a solid chunk of aluminum, carefully bevel each edge and coat it in a long-lasting anodized finish for sleekness and durability in any shooting environment. Set up and make adjustments faster and easier than ever before with the Beastcage’s mechanical power/volume buttons, quick-locking lens mount and rubber-padded phone housing

Ready for anything  

The Beastcage can be as much or as little of a cage as you’ll ever need. Whether you’re looking for a simple rig to attach your phone to a tripod or mount lenses. Or need a full-featured rig with grips, lights, microphones, and monitors for your next Hollywood film. The Beastcage has more ¼”-20, cold shoe and action handle mounts than any other smartphone cage so you can build the rock-solid rig you need without holding back
