The SmallRig HawkLock H21 Quick Release Mini NATO Rail 4640 is designed specifically for DJI RS-series stabilizers, providing a compact and secure mounting interface for additional camera accessories.
The rail features SmallRig's HawkLock quick-release system, allowing compatible accessories such as the SmallRig 4490 Magic Arm and 4637 Monitor Mount to be attached and removed quickly. Its NATO interface supports convenient accessory mounting while maintaining a low-profile design.
A built-in 1/4"-20 threaded hole provides additional compatibility with accessories including monitors, action cameras, lights and magic arms. The rail attaches securely to the stabilizer using two M4 anti-deflection screws, which help prevent unwanted movement and protect the stabilizer's original rail from scratches.
The 4640 can be installed on the left or right side of compatible DJI stabilizers and is constructed from aluminum alloy and stainless steel. Measuring just 2.70 × 2.08 × 1.10 cm and weighing approximately 13.8 g, it adds very little weight or bulk to a gimbal setup.
