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 819-1 Small Hydrostatic Arm spans 22cm and can support up to 2.2 Kg. The 819-1 is the ideal companion for attaching a video monitor to a camera or using as a flag support. Like the 814-1, the pivoting pins are 1/4" and 3/ 8" threaded with one side offering a platform to provide a larger footprint for the equipment being supported by the arm.
