SmallRig Standard Cage Kit for iPhone 18 Pro Max 6901

The SmallRig 6901 aluminium cage for the iPhone 18 Pro Max carries the patented SR-MicroSlide rail all the way around, eight 1/4"-20 threads and "HawkLock" H11 quick release. A 67mm attachable filter backplate and a cold shoe adapter are included.

The cage wraps the iPhone 18 Pro Max in an aluminium frame and turns it into a tool for video, live streaming and short films. SmallRig's patented SR-MicroSlide rail runs all the way around it: accessories slide on in a single move, in about a second, and sit exactly where you want them — cold shoe mounts, NATO rails, Arca-Swiss adapters, handles, and through them microphones, monitors, lights and a tripod. Sliding along the rail is also how the rig gets balanced: shift the heavy piece and it stops tipping in your hand. Besides the rail the cage carries eight anti-twist 1/4"-20 threaded holes, four quick release interfaces compatible with the "HawkLock" H11 ecosystem, and, at all four corners, holes for a wrist strap or a shoulder strap with a cord up to 2 mm. The back stays open, so MagSafe still works and the phone runs cooler; the cage covers none of the buttons, ports, the ultra-wide camera or the wireless charging area. A cover plate and a locking toggle hold the phone — two independent safeguards against a drop. The box holds a 67mm attachable filter backplate and one adapter with a cold shoe mount for SR-MicroSlide; the T-Mount lens backplate, the 17mm backplate and the 67mm threaded filter backplate are sold separately. The line has three tiers, and what differs is what comes with the same cage. Standard (6900 and 6901) is the cage with a 67mm attachable filter backplate and one cold shoe adapter. Creator (6902 and 6903) adds two rotating handles — one of them with a wireless controller — and a second cold shoe adapter. Cinema (6904 and 6905) swaps those for two wooden handles, a detachable NATO rail, an Arca-Swiss plate for a tripod and all three lens backplates (T-Mount, 17mm and the 67mm filter one). Any other backplates and adapters are sold separately. Do not use this product in environments with strong acids or alkalis.
