The Manfrotto Mini Hydrostatic Arm features a revolutionary locking system that produces a firm lock with very minimal effort. The system incorporates a technically advanced ball locking mechanism using hydrostatic action that is based on principles of modern hydraulics. With just a slight turn of the wrist, the arm securely locks in the desired position to firmly hold any camera, monitor, or accessory.
The shorter arm (5") is also the more powerful. The pivoting pin is threaded with 1/4-20" and 3/8" studs so it can be attached to the top of a video camera to support a small monitor or other video accessory with an exceptional load of 7.7 lbs (3.5 kg).
