Description

Create the ultimate iPhone filmmaking rig — your way.
With both the RT and LT Mounts installed, you can fully customize your Beastcage for iPhone 16 Pro or Pro Max (and future models) to match your shooting style. Whether you need a dual-handle setup, a perfectly balanced handheld rig, or want to configure for vertical and horizontal shooting, this combo delivers unmatched flexibility.

Both mounts include standard NATO rails that can be used with horizontal or vertical handles. When removed, the detachable NATO sections reveal ARRI rosette mounts for expanded compatibility with pro gear. Each mount can be installed on either the top or bottom of your cage, and the RT Mount can also be used as a vertical tripod mount. With built-in 1/4"-20 and 3/8"-16 threads and locating pin slots, this setup gives you full control over accessory placement.
