SmallRig Crab-Shaped Clamp with Ball Head Magic Arm - 3757

The SmallRig Crab-Shaped Clamp with Ball Head Magic Arm is a versatile mounting solution designed for securely attaching cameras, monitors, LED lights, microphones and other accessories to a wide range of surfaces and support systems. Featuring a lightweight skeletonised design and a powerful shark-style clamp, it provides strong clamping force whilst remaining compact and easy to transport.

Engineered for flexibility, the clamp incorporates multiple mounting interfaces, including 1/4"-20 threaded holes, 3/8"-16 threaded holes and ARRI-style 3/8"-16 locating holes. It can be attached to round tubes, tripod legs, stabiliser handles, handlebars, tables and other flat surfaces, making it suitable for photography, videography and content creation applications.

The included ball head magic arm features dual ball heads and a secure ball head clamp, allowing smooth 360° positioning for precise accessory placement. An integrated anti-twist system prevents separation between the arm and clamp, while the lower ball head includes a hex socket for additional tightening using an Allen key. Non-slip locking threads ensure quick and reliable adjustment during use.
