Manfrotto Lightweight Hydrostatic Arms feature a revolutionary system that produces a firm lock with very minimal effort. The system is based on principles of modern hydraulics - where force that is applied at one point is transmitted to another point using an incompressible fluid - to create a technically advanced ball locking mechanism.

Gently turning the knob of the hydrostat system compresses the oil in the filled chamber, blocking the movement of the ball. Because the force exerted by the liquid is more constant and evenly distributed than that of standard mechanisms, the locking power is dramatically improved over other technologies. The result of this advanced system is that, 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 development of the innovative Hydrostatic Arms demonstrates Manfrotto's cutting edge technology and dedication to providing equipment for the evolving needs of videographers and motion picture professionals.

The 814-1 Mini Hydrostatic Arm is the shortest arm at 16. 5cm, and is also the most powerful. The pivoting pin is threaded with 1/4" 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 capacity of 3.5kg.
