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.
