The SmallRig 6903 dual-handle kit for the iPhone 18 Pro Max: a cage on the SR-MicroSlide rail, two rotating handles — one with a detachable wireless controller for zoom, exposure and shutter — and a 67mm attachable filter backplate.
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. Both handles clip onto the rail in a second and rotate steplessly, so the grip lands right at any angle; a lever repositions them without tools. The smart handle carries a detachable wireless controller: shutter and record, zoom and exposure compensation, focus lock and a front/rear camera switch. The controller comes off and works on its own up to 10 m away. One kit therefore turns in moments into a dual-handle rig, a vertical rig for portrait video, a light run-and-gun setup or a cage on a tripod. 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.
