The SmallRig 4489 HawkLock H21 Quick Release Rosette Magic Arm (11") is a versatile mounting solution designed for professional camera rigs, allowing users to securely position monitors, video lights, microphones, smartphones, tablets and other accessories.

The arm features SmallRig's HawkLock quick-release slider system, which uses a bi-directional sliding mechanism with automatic self-locking. Internal roll pins help provide secure vertical locking, making equipment installation fast while maintaining a stable connection.

Both ends feature HawkLock NATO quick-release clamps with 1/4"-20 screws and anti-twist locating pins, providing secure attachment to compatible accessories and camera-rig components. The detachable locating pins can also help prevent mounted equipment from rotating or deviating during use.

The arm incorporates 360-degree adjustable ball heads at the mounting ends and a redesigned stainless-steel rosette joint, allowing users to achieve precise positioning. The large locking lever makes it possible to lock the arm and ball heads securely with a single action.

Constructed from aluminum alloy, stainless steel and silicone, the arm weighs approximately 298 g and supports a recommended load of up to 3 kg / 6.6 lb. Its anti-slip thumb lever and padded mounting surfaces improve handling and help protect attached equipment from scratches.
