SmallRig Magic Arm with Crab Clamp Kit 4766 offers a comprehensive shooting solution for users with lightweight devices such as smartphones, webcams, and action cameras. The kit includes a 56cm (22in) adjustable magic arm, a crab clamp, a phone holder, and a 1/4""-20 to 3/8""-16 thread adapter. The adjustable magic arm attaches to the crab clamp with an anti-deflection 1/4""-20 threaded screw, ensuring a secure link between the clamp and the arm. The crab clamp extends up to 50.0cm / 19.7in, adapting to various surfaces and objects within its range, while silicone pads at the swivel tips provide a secure grip without damaging the surfaces. The ball head on the magic arm features anti-skid rubber washers to increase friction, ensuring a tighter lock on the device. The phone clamp is designed to accommodate 7.0 to 10.0cm (2.7 to 3.9in) in width. The 1/4""-20 to 3/8""-16 thread adapter is compatible with microphones for live streaming, podcasting, and audio recording scenarios. Constructed from durable aluminium alloy, the main body can effectively support up to 0.25kg / 8.8oz. We also recommend using the SmallRig Crab-Shaped Clamp with Ballhead Magic Arm (ID 3757B) and SmallRig Portable Dual Suction Cup Camera Mount (ID SC-2K 3566) for shooting with lightweight devices.
