SmallRig Crab-Shaped Super Clamp Kit (with Magic Arm) 4454 includes a magic arm, a crab-shaped clamp, and an action camera mount. One end of the kit features a 1/4"-20 screw for mounting an action camera, monitor, LED video light, microphone, etc. The other end can be clamped to the tube, table, tripod leg, or stabilizer handheld ring directly with the crab-shaped clamp. The joint of the magic arm and the crab clamp adopts the anti-twist design to ensure stability and prevent loosening and falling off while moving. The swivel tip design of the clamp improves compatibility with both flat and rounded surfaces by adjusting the swivel of the clamp tips to ensure equipment stability. The clamp can be attached to surfaces up to 50mm (2.0in) wide and includes built-in rubber pads to prevent scratches and increase clamping stability. The action camera mount allows attaching the Cage for GoPro (3084C / 3083C), the Frame for Insta360 X3 (4088B), and the Cage for DJI Osmo Action 4/3 (4119B).
